    I appreciate the video sir! I got a po101 code even though my 2014 Q50 with 74k miles seemed to be running fine. Got myself some cleaner, and with your video, I took care of it myself! Even noticed a little improvement in throttle response 👏

    These VQ 37 engines are a real gem. I have one in my 2019 370Z and was able to get about 55 crankshaft peak hp more out of it with an intake, exhaust and dyno tune. I did run a mixture of race gas with the pump gas to bring up the octane level from 91 to 94. This enabled the tuner to advance the timing more and extract more power.

    I got the P0174,P0300 and C1109 codes. Is it just cleaning the mass airflow sensors ?

    • @TheAutoTeacher
      @TheAutoTeacher  10 หลายเดือนก่อน

      A malfunctioning mass airflow (MAF) sensor is one of the most common causes of P0174 code.

      If it's only giving you one code for the upstream or downstream oxygen sensor, there's really no need to replace both.

    Thanks for the video ! Currently I do not have any error code on but the thing is car performing very bad and slow response . I’m using k&n oil air filters and seem to over oiled them. Can that impact sensor performance? Should I clean it ? Do I need to clean the trottle Body as well ? Thanks in advance

    • @TheAutoTeacher
      @TheAutoTeacher  3 หลายเดือนก่อน +1

      Your Welcome, over oiling can definitely affect engine performance, which of course depends on how much you over oiled. It could affect your mass airflow sensor and throttle body, but that would be the extreme.Start by installing a regular air cleaner and clean the MAF and see if that remedies the problem.

      Your welcome.OEM is always preferred, it really depends on the price difference. A aftermarket part bought from a reputable place will have a better/longer warranty.

    • @TheAutoTeacher
      @TheAutoTeacher  ปีที่แล้ว

      They become old and brittle and accumulate dirt as the miles pile on, in a warm area try WD-40 and pushing gently down on the tab and wiggle back-and-forth. If that doesn't work, get a small screwdriver or hook and come in from the front.Once released, you will have to use electrical cleaner to remove the WD 40 .

    I replaced my maf sensor because I had the code for the sensor the p010B or something like that lol anyways I replaced the sensor & my car is no longer misfiring during driving but now it doesn't always start the first time I start it. I usually have to try a second time & it'll start. I did get the part from autozone, could that be why bc it's not an oem?

    • @TheAutoTeacher
      @TheAutoTeacher  7 หลายเดือนก่อน

      Getting the part from AutoZone shouldn't be an issue. Have you checked your air filter to make sure it's clean and when was the last time your spark plugs were replaced?

    • @gsteel98
      @gsteel98 4 หลายเดือนก่อน +1

      These cars are very sensitive regarding sensors. When I replaced my crankshaft sensor with doorman it worked for a few months then gave problems on and off til i put in a denso sensor. The original denso I put in after the original failure was broken by the flexplate so my mechanic swapped a doorman in I didn't choose it. Get denso, hitachi or ngk when it comes to sensors nothing else unless you do research. Z1 has been a tried and true site for aftermarket parts. Rockauto has oem MAF sensors as well I think 60 each

    • @TheAutoTeacher
      @TheAutoTeacher  10 หลายเดือนก่อน

      Yes, a PO102 could be a Faulty mass air flow sensor.
      PO102
      - Intake air leaks
      - Dirty mass air flow sensor
      - Dirty mass air filter
      - Mass air flow sensor harness is open or shorted
      - Mass air flow sensor circuit poor electrical connection
      The PO 300 is multi misfire, which is probably caused by your P102 code. I would address the PO102 first.

      Not sure why that would be, if you remove the two screws usually it pulls out super easy. There's only a small rubber seal, and it's made of plastic so there wouldn't be any corrosion. Try using pliers if you're replacing it with a new one.

      Potential causes of the P2A03 coming back are burnt, broken, or disconnected wires leading to and from the oxygen sensor.
