Thanks Roy: You are an excellent mechanic and teacher, providing lots of good practical direction and advice along with useful images and graphics. My girlfriend's 2000 Camry CE was having sporadic hesitation problems, sometimes while idling and at low speeds, but mostly when the engine was stressed during major acceleration and/or climbing hills. The engine check light also had been on and occasionally flashing. After consulting our next-door neighbor who was a mechanic at a local Toyota dealership, I replaced the spark plugs. This helped immensely and while doing so I discovered two plugs were loose, especially the 2nd cylinder, with lots of oil that had seeped up onto plug and into wire harness. I thought this alone might be the problem, and after replacing the plugs the engine ran much better. Our Toyota mechanic neighbor had said "It sounds like the motor might not be getting enough spark, fuel or air." So then I replaced the fuel filter (original and car has 228K miles). Next, I replaced the air filter. Then I replaced the in-tank fuel pump and pump strainer (also original and dirty). This eliminated many of the problems, but during a 60-mile trip which included interstate and local roads, we still felt maybe three brief periods of engine hesitation. Hum? I thought that maybe it simply was a matter of some air bubbles that got into the fuel line while replacing the fuel filter. I figured that these small air pockets eventually would work themselves out as we drove the car and used more gas. However, when I stopped at our local convenience store I was prompted to notice a stranger's Jeep parked directly across from me with license plate MIS-FYRE. What are the odds? How synchronistic, and since I don't believe in accidents, I visited TH-cam again and noticed that some other folks with 1997-2001 Toyota Camrys had engine "MIS FIRE" problems related to bad spark-plug wires. A few of these folks, like you, had an electronic diagnostic tool whose codes indicated MIS FIRE problems in various cylinders. Often caused by old and/or damaged ignition wires. Some other knowledgeable folks also said engine check light and hesitation problems might be connected to a bad O2 (oxygen) sensor, especially the "upstream" sensor. Anyhow, so we ordered a set of new Japan-made spark plug wires that are supposed to arrive at our house later today. Along with a new upstream O2 sensor and universal O2 sensor removal tool that are supposed to arrive later this month. Lastly, I'm also going to change the transmission fluid, tranny filter and tranny pan gasket. At over a quarter million miles I think my girlfriend's car deserves the attention. Anyhow, thanks again Roy. P.S. I'll let you know how things work out after changing the wires and later the upstream O2 sensor. Sincerely, Jeff Martin & Suzanne Fisher in rural Aylett, Virginia.
Hi Roy : There are NO o-rings in there. The spark plug tube has threads on both ends, one end is threaded into the cylinder head. the sealant on those threads is bad. If you look into the tube just at the top of the spark plug you'll see the seam. that's where the tube meets the head. That's where the oil is getting in. The fix : remove valve cover unscrew the tube , clean, re apply new sealant screw back in no more oil in tube. there are videos how to do it......good luck
@@jasondroyd9373 There are O rings on top of the valve cover. They're rubber O rings that have a metal washer on top. If you buy a valve cover gasket it usually comes with the O rings. I had the oil in spark plug tube problem and replaced the O rings. Not a drop of oil in the tubes since replacing the O rings. I did the valve cover gasket at the same time.
If you’re standing at the front of the car looking at the engine, going closest to you to the furthest, it’ll be 1(closest to you)-4-2-3(furthest from you). I hope that helps and thanks for watching 🤙🏽🤙🏽🤙🏽
@@RoysGarage808 so from the side coils it’s labeled 1,4,2,3. So now do we plug that in the same way on the cylinders at 1,4,2,3? Because I have mine plugged in order from 1 to 1 4 to 4 etc… but I’m guessing it need to be coil 1 to cylinder 1. Coil 4 to cylinder 2. Coil 2 to cylinder 3 and coil 3 to cylinder 4. If that makes sense. And I’m also confuse because we know that cylinder one is passenger side. So it’s 1-4 but on the valve cover it shows 4-1?
@@TheRealYbJr I’m don’t think I’m understanding you completely BUT in order to avoid this confusion, I always take one old one off on one side and put a new one on, then follow the line to the other end to remove the old and install the new. It’s a tedious one-step-at-a-time process but it makes sure to avoid all confusion and guarantees everything gets plugged in correctly. Hope that helps and thanks for watching 🤙🏽🤙🏽🤙🏽
@@RoysGarage808 yes so i Install new plugs and all that and it was still miss fire. I had it plugged in order 1,4,2,3. When we stand looking at the top of the valve cover, the top of my valve cover is in graved 4-1. What does that mean. Because we know it’s 1-4 cylinder wise. I am confuse with the 4-1. Because standing looking at the engine we know the farthest to the left is cylinder 1 then 2,3,4. But again that 4-1 kinda confuses me. I hope that explained better. Thanks and your welcome

You should zoom in. We need to see how you separate the wires from the locking mechanism with your flatheads screw driver. Not really helpful. Hope you fix it in the next video

Glad I could help and looking forward to hearing how it goes! Thanks for watching 🤙🏽🤙🏽🤙🏽
Great video. Damn, you move fast! 😜
I’ve got a 2000 Camry LE which is giving me some issues at the moment and I think it’s plug related.
Thanks again.
thanks for the great info you share here, i learned more than what i was looking for
Thanks for watching 🤙🤙🤙
Hey Roy, if you pull the valve cover you can replace the seals on those tubes.
Always learning! Thanks for watching 🤙🏽🤙🏽🤙🏽

Thanks! That was super clean and easy. Just bought one of these...almost like new! Nice to have a vehicle that I can actually work on again.
Ok I’ve loosen my spark plugs but they are not coming out. What should I use
What's the order to plug in the spark plug wires from the side?
If you’re standing at the front of the car looking at the engine, going closest to you to the furthest, it’ll be 1(closest to you)-4-2-3(furthest from you). I hope that helps and thanks for watching 🤙🏽🤙🏽🤙🏽

Any help..... on the wire connection order?????

Jus not sure bcuz facing the engine spark plugs are 1-2-3-4 left to right but connecting to the ignition coils are different????
this is good advice
Thanks for watching 🤙🏽🤙🏽🤙🏽
Do u have to do a reset with the change of wires?
All the fours always have oil inside
❤
Good job bos
Thanks for watching 🤙🤙🤙
My wires are stuck in the blockhead

Thanks for the feedback and watching 🤙🏽🤙🏽🤙🏽
