I've had 2 cars now after doing the ghost cams and returning to stock for a long trip. Then ive tried to load the cammed file again if found it will not cam like it originally did and run like crap and stall.no alterations had been made to the files since . I've even tried starting from scratch but no luck. What am I missing . Cheers

Maybe fouled plugs?

I would check the long term airflow and fuel trims before and after also. The computer might be getting confused with the false lean idle and making it run excessively rich.

Try turning off long term fuel trims and see what happens as an experiment.

Personally I'd run it open loop if you want to get the idle better. Otherwise the overlap will induce a false lean reading which will eventually peg the LTFT at +25 and spit fuel out the pipe.

Make sure you retune the overlap SD adder tables at high overlap as well to help the PCM have a better starting point.
