Well i wnt out tonigt to do some ricer smackdown and didnt see any so i raced a ls1 trans am had no problems keepin up but when it was all sayed and done i started to cruise around again but when i went half way down or full on the throttle didnt get any power like it should and drove home it could barely make it up the hills. So i check it with the code reader and all i had was o2 sensor crap but the check engine light wasnt even on. Sorry for the long story but anybody got some ideas

 

maybe the o2's are bad. or something on the maf?

 

could be gonna let cool down overnight then see what it does

 

What codes did you get? If you have a pending O2 sensor code, the sensor may be on it's way out and already giving the PCM false info, but not tripping the light yet. That would cause a loss of power...
