Super weird readings and cel
Hey guys don’t know if yall have been dealing with this ever, I bought a used Wrx and for a month I had no problems. I got a few things done to it for preventative maintenance once I got it I had the oil changed the spark plugs, changed the tranny fluid and rear differential service and had the coolant flush. I had walnut blasting and they ported my TGV housing. After a week of that service being done. My idle was acting weird at stop sign. My idle would go and fluctuate at lower RPMs almost like it’s stalling out. I went back to the shop that did all my work and they said my air fuel ratio sensor was acting up. It goes like water on these WRX’s FA 20s so I gave him the go ahead to change it. And for two weeks, it was great and then I went on vacation for two weeks so the car sat. After I came back, I started driving it, and I’ve noticed that a week into driving it looking at my Cobb logger all of my air fuel ratios my air fuel correction in my air fuel learning has been really high and fluctuating. I know this car has headers, catless downpipe, invidia exhaust, Cobb sf intake, bigger intercooler, EGR and tgv deletes. A few days ago my check engine came on saying that the system was running too Rich when I try to clear it it would be fine for a couple of days and then it would come back on. I just bought the mass airflow sensor and going to be putting it on this weekend. I’ve read that’s to fix the most problems and if not, I’ve also read that the turbo inlet is also an issue on these if running Rich so I ordered that as well. I will put them on this Saturday, but I just want to know if this is going to the right direction what do yall think it could be
