LT1 start up problems

When I start up my car the ses light is on and idles like crap. It's hard to keep running and if you give it any throttle it's like a delayed reaction. It will die and cranks right back up with no ses light and runs fine. I have used the free scan it's not showing any codes. Any ideas?

It's easier for us to provide accurate responses if we know the detail of your specific vehicle. Not all years of the LT1 are the same, particularly with regard to scanning the PCM.

Re: LT1 start up problems

Are you running the 1995 PCM? How are you scanning for codes?

Yes I'm running the 1995 PCM. I'm scanning using the free scan (Gary Doug) with my laptop and cable.
