92 rough idle/warmup
I have a problem where it is a rough idle on startup and takes a while to get warm and running good. On these start ups its running very rough where idle drops low then regains and so forth. So low you think it will stall and turn off. I bought it a couple months ago and it def has some mods including a F303 cam. I know it is a rough cam but right now I still cant imagine it would be that bad at idle. I am not sure if it has been chipped.
Once it is warmed up it is great, but it does take a while to get there.

It runs rough for more sometimes will sit in driveway for 5-10 before we get anywhere. As far as O2 sensors....Prior owner took out all.....i mean everything for emissions. Luckily 2 more years and I too wont have to worry about it anymore either

I am sure you still have your O2 sensors. That is if you still have all the computer controls and the stock Fuel Injection system, of things would not work. I am in the process of removing all of my emissions crap, I am replacing my stock H pipe that has the Cats with one from LMR and it has the spots for the O2s.
I have been going through some idle problems and I pretty much got it figured out. It has turned out to be my ICA Valve. First try cleaning it. Here is a link that will help.

You should also do a KOEO/KOER test. See if you have any codes and go from there. I stared with these and went from there.

I felt just like you a few months ago when those very links were suggested to me. The I just read them step by step as I did the test, and it turned out to be easy. Now I just do the KOEO/KOER tests like second nature whenever I am tinkering on the car or change something.
Listen, I just bought this car last May. My toys before it were a 72 Chevelle wagon and a 79 Chevy C10. Both carb cars. Talk about a fish out of water gettign rid of those cars and now having, To me (With a small laugh) a late model computer car. So I was very, very confused. If I can figure it out, anyone can. You can get a pretty inexpensive multi meter at Harbor Freight. I got a real high dollar one I bought from the Mac tool guy when I was an auto tech back in the 90s. My roommate picked one up for $5.00 on sale at Harbor Freight and I use his most of the time. I might get one for myself. Its allot smaller then my Mac tools one.
