hi does anybody have an idea what problem i have with my car.
I put an ls1 1997 from a Corvette dbw and a 4l60e from a Camaro 2000.
i bought a harness from psi and a flashed pcm 411 from psi,
ive got a new mafsensor,mapsensor,knocksensors and harness,
throttlepedal from 2001 Corvette,tacmodule from 2002 Corvette.

and now to the problem.
it start and idles perfekt and you can run carefully and it works fine.the transmission gears up and down perfekt.
but when you push the throttle to go faster it stalls and runs poorly and if i lean of the throttle it runs fine.????????????????????
i hooked up a tech2 yesterday and Everything was fine exept that when i start the Engine ive got a code. " high idle output".
And then i took away the negative on battery and let the car stand for like 5 hrs and then i took it for a drive and it worked fine until it get warm and then it started again.grrr
