running rough when started
I have a 93 LT1, it starts just fine, but it requires about 3-4 minutes of warm-up, otherwise it spits and sputters for several blocks, will a tune-up fix this? My vette has about 60k miles and always garage kept. I bought it about a year ago and do not know it's mantenance past.

start by getting the codes before blindly throwing parts at it.

okay, I ran the codes...
when I placed the short in A B pins I got
12, 12, 12, 15,15,12,12,12
when I placed the short in A and H
I got...
1. c12
4. H15
9. ---
1.0 nothing, no code or dashes
Just a note, I have unhooked the first to fourth soleniod on my 6 speed tranny, just in case that has anything to do with that code. I noticed where it said 4 was for the PCM module.
So, can you tell me what it is saying....and can I do something to get the SES to reset on the dic?

I searched another tread and found out how to clear the codes.....only problem is the same codes come back as soon as I start it up..... so, I guess I am back at my last question....what does code 15 and H15 mean?
