I did a cam install back in mid-October and have had ZERO problems with it after 3000+ miles. The car ran awesome with stock programming, no TB hole enlargement. It has never set any codes or done anything at all weird. Today on my way to work, at every stoplight it would idle down and die unless I kept my foot on the gas a bit. No SES lights, all gauges normal. I have never beat on the car and have only taken it to the stock rev limiter 1-2 times since the cam swap. I am mystified. Any opinions are welcome. Thanks!

Oh... car is 2000 SS, M6, regular bolt-ons, no headers, Comp XE 218/.563/114 cam, 918s, Comp pushrods.

 

Some codes don't set right away. In a few more driving cycles you may have a code. I guess you don't have a diagnostic scanner?

You drive this car everyday, correct? And yesterday it didn't do this at all? Any significant changes in the weather?

I'd wait a few driving cycles to see if an SES light shows up. If not and the problem is still there I'd reset the PCM and do the idle relearn.

 

BTW, moving to Computer Diagnostics and Tuning...
