Do you have access to a Gunson Gas Tester or an LM1?
If so check your CO% at hot idle and set it at 3%.
Yeah, that's what I was thinking since it runs fine while cold. I'll have to look into buying or renting a tester.... if they are affordable. Before I do anything, I am going to let it idle warm and then pull a few plugs and take a look. The strange thing is, it was running fine for the first week I had it, cold or hot, but then again I've been driving it easy and maybe the plugs are either too cold or mixture too rich, or both? Thanks for the input, I appreciate it and will post later once I troubleshoot some more.
