Need some help(rough idle, o2's) Ok car is a 99 vette. Vararam, B&PRT's, gears, and a nx wet kit. Stock tuning and some tr6's.
Now the last 2 times ive been to the track ive tripped the 02 sensor code. 10 PCM P0138, 02 high voltage bank. The check engine light has always come on after my 2nd run. Then after driving around for a few hrs, it'll go away. First time at the track was the 100 shot, last time was 150.
Now when my car is in Neutral or Park it will idle around 700 rpm just fine. But when its in D and im holding the brake, the idle is rough and jumping around 500-600rpm.
Ok so i guess my question is how can i avoid tripping those o2 codes and whats causing the rough idle? Fouled plug?
Any help would be appreciated.
