69 camaro ls1 swap help needed. IVE GOT THE LS1/6MT RUNNING IN THE FIRST GEN. RUNS LIKE CRAP THOUGH. F/P IS GOOD 55-60 PSI, NO MILs. CAR HOLDS VERY LOW IDLE AND HAS VERY BAD THROTTE RESPONSE. WHEN I TRY TO HOLD THE RPMS UP, THE ENGINE SPEED DROPS THEN PICKS BACK UP TO WHAT I WAS HOLDING THE RPMS AT. THIS IS MY SECOND LS SWAP AND IVE NEVER SEEN ANYTHING LIKE THIS. ANYONE HAVE ANY IDEA WHAT COULD BE GOING ON?

You must have tuned on all CAPs. Thats whats wrong. Are you running a MAF? Are you usre the MAP is connected? Are the plugs new? Has this engine sat for a while? Are you usre this engine was in running condition? Oil pressure? Did you do a compression check?

thanks for the info, i sent the ecu and wiring back to the programming company just to double check everything, there was a fuel tank pressure code that came on that was supposed to be gone. well see what they come up with. whats the best way to clean up the injectors?
