MAF trick? You mean cleaning the MAF sensor? You can clean any MAF sensor.is the MAF trick doable on the 2011 wrx model? Im getting a misfire code on all cylinders and I feel like when I idle the car feels like its shaking. I get the feeling the ECU or something might be mis-reading the air flow or something.
OK, new plugs, swapped coil packs around, but now I have 2 misfire codes. And, they didn;t follow the original #2 pack...Ugh.I just started chasing a P0302 with the bouncing motor on my '02 with 8x,xxx miles with a stock motor and Cobb AP Stage 1 map.
A year or more ago I got the P0302 and swapped #2 & #4 coil packs. Code went away.
This time, to start, I'll put new plugs in and swap the coil packs around and see what happens.
Does that sound like a good start?
PS, I also had a P0171 a couple weeks ago that seemed to go away with MAF cleaning and some post-MAF intake tube clamp tightening.
Thanks for the input, but as posted earlier, it is actually running BAD, it's not just a code with no symptoms...You can easily check the connectors with a multimeter or test light but you are on the wrong trail. I highly doubt the issue is power to the coils since the car is actually running. Even missing 1 cylinder would be extremely obvious.
Here's what I would do: Start your own thread, do some data logging, and post your data logs.
