Have a 2021 wrx premium 75k miles she runs great honestly… was looking to do an intake and tune soon. I purchased an accessport, so I could get an idea of the current numbers and installed it yesterday 5/17.

I flashed the stage 0 tune and the DAM started at .8 then after I let the car idle for 15minutes, drive normally for 15 minutes to warm up, I got on the throttle a little bit, like 1 or 2 WOT pulls. By the time I got home DAM had dropped to .355 or something near that. Since then there was been movements up and down… it does try to get loser to 1 when I drive normal to mid throttle

I took a few pics of the numbers at the end of my drives and attached them for y’all’s reference.

AGAIN car drives me perfect and honestly wouldn’t have questioned any of this if I didn’t get the Lol but still glad i did. I’m getting my spark plugs done thursday, so if there is anything I should ask the shop to take a peep for please let me know!!!

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

I wish I could do everything I want to this car but unfortunately I’m not made of money and I gotta do a little at a time.
Torn between upgrading to STI headlights, getting a nice front splitter, or doing something about the base model fog light bezels. Going for a nice simple OEM+ look. Open to ideas…

2015 premium 59k and absolutely immaculate. Even came with the valet key. Service history was solid. Whoever owned this car took extremely good care of it. Paid little over $20k.

PLEASE READ DESC.

Hello every one thanks for all the help on my last recent post (https://www.reddit.com/r/WRX/s/Hm8dbHC3Pa). I decided to unmarry the accessport my only concern is that ever since the issues occurred my engine/ car/ drives have all sounded fine, felt fine, looked fine it was primarily the numbers that were my “Issue” so now without the accessport is blind to DAM, FBK, FKL and all other gauges so how can i go about maintaining my car healthy and back up again? How do i check/know?

Also me and my brother who has an 06 sti took it for a little drive and he said he noticed/ heard some misfiring happening so i recorded a clip of my exhaust to let you guys hear and tell me what you guys think. He says it’s probably my coil packs or something with my spark plugs and all that stuff but let me know! (Keep in mind i have a axle back muffler delete and this is a warm idle)

Also apologies for not saying sooner i drive a 2021 VA WRX base FA20 2.0L MT, bone stock besides an axle back muffler delete.

Thoughts? shoukd i keep driving it? i have a diagnostic appointment Monday at a subaru dealership hopefully they can put my mind at ease also if you guys have any suggestions on what i should tell the dealer to check specifically (will already be telling them to check my coil packs and spark plugs)
