modifications I have done to my car (2003 WRX):
-silencer delete. left the end that got cut open.
-3" S*RS CatBack exhaust. From cat all the way into the engine bay is stock, downpipe uppipe all that.
-dash replaced with LED lights.
-emblem repaint and de-badged.
however irrelevant they are all listed.
today check engine light came on and I got codes pulled at Autozone. Reads as follows:
Fuel Level sensor circuit low input
1 open or short circuit condition
2 poor electrical connection
3 faulty fuel level sensor
System too lean- bank 1
1 faulty MAF sensor
2 large vacuum leak
3 low fuel pressure
4 plugged injector or cylinder misfire
1st one caused by low wattage LED bulb in dash for fuel level ?
it came up before and then shut itself off. this time the second code popped up though.
2nd code I thought was because I didn't seal up the new exhaust very well, I cracked one bolt. But I used 4 gaskets and misc. hardware to get it down to almost no leakage. would that explain the large vacuum leak? my mechanic buddy says that it wouldn't be that because it is after the MAF sensors in the stock cat. is the exhaust enough to spool the turbo earlier and cause it to run lean?
I'm not super savvy with cars but I'm learning and I don't understand why this would happen now, all those modifications have been the same for 3 weeks now, no further mods.
Please help, thank you and sorry for the lengthy (but thorough!) post and my lack of proper grammar and punctuation.
