2001ws6-500hp

this pst weekend i put the new heads and cam in. had a few problems after, car wouldnt start but found a ground wire off at the back of drivers side head. fixed the problem.

ok so now the car is running and all. got it to idle right at 600 rpm. put it in gear with ur foot on the brake and stays idleing with 0 bucking or surging. everythings good. except. when i drive the car, it will run good while its below like 180 degrees. after it warms up, its like i have 0 power at all. i experienced this once before. it happened when my o2 connectors got wet. so i looked at the 02 connectors and seen one was melted to the header. oops, so i took it off and cut out the melted section of wire out and butt connected it back, tried to drive the car and car ran good. just when i thought i had it fixed, it did it again, fml.its like the rpms dont wanna climb. please help with any suggestions as to what this might be!!!!!

no the throttle cable isnt off lol
thanks

The temp thing is weird, I don't see why its ok under 180 and then its fucked above 180.

Maybe something simple like spark plug wire(s) touching an exhaust manifold/LT pipe. Arcing will kill power while trying to accelerate in the higher rpm's.

If it directly correlates to temperature, you should check your coolant temperature sensor: http://www.wellsmfgcorp.com/pdf/Counterpoint2_2.pdf
