If I slightly flash the rpms (while in drive) to 2500-3000 and then let completely off the gas, the rpms will just fall to 200 and then the car will knock off.

Its very annoying when turning the wheels over in the waterbox. As soon as I let off the gas, knocks off. Same thing for burn out. Im having to ride the brake to the starting line and keep it stalled up to 1500-2000 to keep from knocking off.

Normal driving it does fine. Cold starts = knock off until > 160*.

I performed the idle relearn procedure, but it did not work. Afterwards, I powerbraked it, and just flashed it enough to just break traction. Then I let completely off the gas....car went rpm hunting and knocked off.

Thanks,

You probably need to work on the tune with the throttle cracker. There are probably other areas in the tune that need adjusting as well.

How much slower is the 97 computer vs the newer c5's? I was told that my computer is having problems keeping up with my motor.

Thanks,

The 97 computer calculates when to fire 4 spark plugs and when to open and close 4 fuel injectors each rotation of the engine. Your problem isn't because the computer is too slow.
