Hey i have a 2002 wrx that i bought about 5 months ago. As of about 2 months ago my car has been running pretty bad, when idling it idles at about 500 rpms and sometimes drops to 300. Also if I am at a complete stop and i push the clutch in to drive a couple feet "like in a drive through" the car starts to bog out really bad and sometimes dies. Also first gear seems sluggish but other gears are fine. The car also came with a cobb accessport and is tuned but i didnt do the tuning so I am not exactly sure what it is tuned to, just being honest. I tried to reset the ECU to stock but the AP said FAILED, PLEASE TRY OPERATION AGAIN. I do not know what to do!! Please any help would be aprecciated.
My mods is a full exhaust, and a cobb accessport.
