Replace hardened or cracked hoses with fresh ones. You can use generic cut to size. Zip tie the ends. For high mileage consider changing throttle body and intake plenum gaskets. I did that and car feels amazing. Before had less power and acceleration.
this video is extremely helpful for us diyer's that have mechanical abilities. I'm worried about the intake manifold on my son's 2008 civic. The engine was replaced the manifold was disassemble'd and cleaned. I do have a PO507 code and the idle is a bit erratic. There are internal rubber gaskets that can also leak I guess but can they be tested? My gut tells me to remove this and replace all rubber gasket's inside and out. Something I should have done while the engine was out. YTer's like yourself sure do help us diyer's find, test, repair, just about anything. My advice is to search any and every video related to learn more. I thank you and others as a form of education lowering repair cost's. Most importantly this is a father son project that give's a strong bond.
It's great to hear you found this video useful for your 2008 Civic DIY project! You're doing a great job working together on this project and creating a bond. According to your description, it's a good idea to replace the rubber gaskets both inside and outside the intake manifold, especially if they are suspected of causing the erratic idling and the P0507 error code. You can test for leaks by using methods such as smoke testing, or spraying soapy water while the engine runs to look for bubbles. I wish you luck and hope that your repair goes smoothly.
Thanks for your comment, I appreciate. Where to connect smoking machine is through the Vacuum line or intake manifold, then run it to detect leaks as described in the video.
Thank you for the detailed video. Can a vacuum leak cause a p1138 code on a 2005 Nissan Sentra? Service soon engine light came on OBD reading. Swirl control valve
@@exoniviews Ok. Thank you for replying. I was told by a half baked mechanic that a vacuum leak will not cause the p1138 code he didn't even check. I will have a real mechanic take a look at the vacuum hoses. I appreciate your response. Thank you very much.
Great vid! I have this maddening problem, every yr, when it gets cold. I have an ‘08 pont vibe (toyo engine). The chk engine light illuminates and I get a po107 code - too lean, bank one. I must stress that I have NO outward symptoms and it purrs like a kitten until it extinguishes, either thru my code reader, or by itself, when it gets warmer. I’ve tried all yur suggestions and pretty much ruled out a vac leak, bad o2 sensor etc… What advice can u give me to try and remedy this yearly dilemma. Thx again👍
Very sorry for late responds. Considering your annual cold weather P0107 code issue on your '08 Pontiac Vibe, despite ruling out common causes like vacuum leaks and faulty O2 sensors, you should also consider checking the intake air temperature sensor and try cleaning the mass airflow sensor, as it might be sensitive to cold conditions affecting air-fuel mixture. Potential issues, as extreme cold can affect sensor performance.
@@exoniviews Great. I’ve cleaned and clean my maf sensor on a regular basis. I may just buy a nu one considering the relative smal cost. C if that works. Thx!
Thank you! 🚗 It's possible that a vacuum leak could cause high RPMs. Check for any hissing sounds around the engine bay and inspect vacuum hoses for cracks or disconnects. A smoke test can help pinpoint the leak if needed.
Intermittent lean codes at higher RPMs often point to vacuum leaks or fuel system issues. Check for leaks in the vacuum hoses and inspect the fuel delivery system for problems.
@@exoniviews thanks will do. Any chance a cheap Thornton obd plug and play tuning chip could cause this at all? One was in the truck and was removed 2-3 weeks prior to the start of this happening.
@@lh98 It's possible that the cheap OBD plug-and-play tuning chip could have contributed to the intermittent lean code issue, especially if it was removed shortly before the problem started. These chips can sometimes interfere with the vehicle's engine management system. Removing it was a good first step, but I'd recommend thoroughly checking for any lingering effects or issues it may have caused.
Have a po302 on my Subaru sti. So far no luck with a smoke machine. Done all swaps, compression, leakdown, o2 sensor replacement, noid test on injector connector what else can I do
Try to double-check the ignition coil and spark plug for cylinder 2 to ensure they're working properly. Even though the noid test showed the injector is getting a signal, it could still be clogged or malfunctioning, so you may want to clean or replace it. Also, inspect the intake manifold for hidden vacuum leaks, and examine the wiring harness for any damage or loose connections.
Hello, I know I’m abit late hahah but my VW GOLF MK7 sometime when I drive off after 30s when I stop at a junction, my RPM sits below 1k just on the line. And the fan kicks in. Also I’ve notice I have a leak around the engine and ‘MAF’ side. Also since I changed my timing belt and water pump my car started making a rattling sound. Do you know what could it be. I know it’s hard to understand what I said but if u know something help pls haha
1. RPM sitting below 1k and fan kicking in; If your RPM is low when stopping at a junction, it could be related to the idle control system. VW models sometimes experience issues with the throttle body or the idle air control valve. A dirty or faulty Mass Air Flow (MAF) sensor can also cause rough idle or fluctuating RPM, especially if you're seeing a leak near the MAF sensor. Address that leak, as it might be causing unmetered air to enter the system, affecting idle. 2. Leak around the engine/MAF side: If you’re noticing a leak, it could be vacuum-related, which might be causing the irregular RPM and idle issues. You should inspect the vacuum hoses, intake manifold, and the MAF sensor seal for any leaks. Also, a coolant or oil leak could cause engine performance problems if it's affecting critical engine components or sensors. 3. Rattling sound after timing belt and water pump change: A rattling noise after changing the timing belt and water pump could indicate that something wasn't torqued or aligned properly. Double-check that the timing belt tensioner, pulleys, and water pump were installed correctly. The noise could also be due to a loose belt or a misaligned tensioner, so it's best to have the belt assembly inspected again to rule out any potential damage
my honda with idsi engine shows p0131 o2 sensor low voltage inspect sensor its good wiring also good what could be the reason i put another ecu but same code pops up what could be the reason help me sir
The P0131 code (O2 sensor low voltage) can be caused by several issues beyond the sensor and wiring, including: Exhaust leaks before the sensor, A vacuum leak causing lean conditions, A faulty fuel injector or fuel pressure issue, A bad ground or connector issue elsewhere in the circuit., The sensor itself may still be faulty despite appearing fine. Check these areas for further diagnosis.
@@exoniviews sir had inspect and i found that when i start the engine i checked the o2 sensor wiring voltage the 2 wires which is heater circuit in one wire there is 12v positive➕ from ignition but there is no ground comes from pcm i checked with multi meter and then with the tester i want to know that when me start the engine heater ground will come immediately or it will take time??let me know sir thanks for your precious support
@@hayabusagsxrlovers1374 If the ground for the O2 sensor heater circuit isn't activating immediately you start the engine, but rather delays, That means there may issue with the pcm or wiring. Try checking the following areas; Check PCM function and ensure its functioning correctly, as it controls the ground. 2. Inspect Wiring to Verify there are no breaks, corrosion, or damage in the ground wire from the O2 sensor to the PCM. 3. Check for Fault Codes, Scan for any error codes related to the O2 sensor or PCM that could indicate the issue. 4. Test the Relay or Fuse and ensure the fuse and relay controlling the O2 sensor circuit are not faulty and 5. PCM Reset or Reprogram: In rare cases, resetting or reprogramming the PCM may help if it’s a software issue. If none of these resolve the issue, replacing the PCM might be necessary.
Ok, It sounds like the gurgling noise from your Škoda's dashboard during ignition might be related to trapped air in the cooling system. This can happen when there's air trapped in the heater core or coolant lines. A common remedy is to "burp" the cooling system to remove air pockets. Here's what you can try: Make sure the engine is cold: Never open the radiator or coolant reservoir cap when the engine is hot to avoid burns. Park on a level surface: Ensure your car is on a flat and level surface. Open the coolant reservoir cap: Slowly open the coolant reservoir cap (if equipped) to release any pressure. Inspect coolant level: Check the coolant level in the reservoir. If it's low, add a mixture of coolant and water to the recommended level. Start the engine: Start the engine and let it run until it reaches normal operating temperature. Keep an eye on the coolant reservoir during this time. Bleed the system: Sometimes, there are bleed screws or valves near the heater core or on the coolant lines. Consult your Škoda's owner's manual to locate them. If available, open these while the engine is running to release any trapped air. Top off coolant: As the engine runs, the coolant level in the reservoir may drop. Top it off as needed. Close the cap: Once the gurgling noise stops and the engine is at operating temperature, close the coolant reservoir cap securely. Monitor for a few days: Keep an eye on your car for the next few days to ensure the noise doesn't return. If it does, you may need to repeat the process or have a professional inspect the cooling system for any leaks or issues. Remember to follow safety precautions and consult your Škoda's specific manual for guidance. If the issue persists, it's advisable to have a qualified mechanic examine your vehicle to rule out any underlying problems.
Gas Vehicles may be obsolete too much money to keep them running even after your done with car payments you still have to shell out money for all kinds of repairs and your car devalues as soon as you take it out of the Dealership. Meaning you just burdened yourself with a huge debt in a Debt driven society.
I think that’s a waste of time. That’s not going to catch say a hose thats hardened or cracked and lets air through only under pressure. Just change all suspect hoses and tie wrap the ends. It also won’t catch a gasket that leaks only under pressure/vacuum.
My cruze 2 time off engine when i strt engine in morning time.. Aftr that engine run or no stop bt power going loss sometime full rpm only 2000 rpm an sometime normly rpm gi higher in Desiel engine

How about an intermittent lean code that only comes up on higher rpms (idle is fine) either get po300 or po171 po174 every day or every 2 days.
