2001 trans am ls1 motor in 1968 firebird. I stroked the engine to 383, from the very first start I' ve had a cam sensor problem? Replaced sensor, sensor plug, checked wiring to computer. The car runs good for about 3-4 minutes at cold start up, then won't run past about 2400rpm after that. my tuner recorded a 20 minute ride. It showed a spike(no signal) from cam sensor. He says it might be the computer. any ideas? Thanks

 

You are most likely to get better information in this forum.

Thread moved, good luck!

 

Does the sensor wire run directly to the pcm or does it loop to a connector by the egr or r/f head. If you havent already, ensure that 5v and sig wires arent swapped.

 

The Power/Ground wires need to be switched.
