Re: LT1 breaking up

I have had loose connections at the ignition control module cause something like this. I found the culprit by jiggling the wire and causing it to sputter.

Re: LT1 breaking up

Could be a bad EGR valve as well. Does it rev no problem when it's cold?

Re: LT1 breaking up

Sounds like the classic opti problem. Have you recetly washed down the engine or had coolant leaks near the opti? Here's a great place for more information...
