Please Help! Code 1515 and 1516
Please Help! Code 1515 and 1516 Hi Guys,
I just had my o3 Vette Dynoed at NLP by Mike Norris, I installed Dart 225's Fast Intake and LS2 throttle body with plug and play,at idle the car goes into reduced power mode and throws codes 1515 and 1516, Mike seems to think it is the throttle body blade opening and the tach module doesn't match it. I am not a tuner nor do I know anthing about tuning but if you guys have any ideas that could help me it would be greatly appreciated. It also doesn't happen when the car is cold only after it warms up and I drive for 20 minutes or so, it seems like the idle will jump up a little bit then go back down and the motor sounds uneven and then it will throw the code.
