I was testing my car out and missed a powershift from 2nd to 3rd. It revved to about 6K, but that shouldn't be a problem in and of itself. Anyway, I drove a couple of more miles back to town and when I came to a stop I noticed the motor was missing a little. I don't know if this is related to the rev, but thought I should mention it.
If I drive it at low RPMs it misses, but if I get it up to wide open throttle it runs fine.
I pulled a plug (#8) and noticed it was blackish. I decided to go through all the plugs one at a time to see if a fouled plug was the problem, it wasn't. I noticed that plugs from cylinders 4, 8, and 1 were blackish, I think the others were OK color wise. Another thing I notice is that the primary side of my Edelbrock 1407 is a little black too. Is this an indication that I have my idle set too rich?
Next I tried all the plug wires, but no help.
I decided to listen to each side of my exhaust, they are independent sides with cheap little 18 inch glass packs. I couldn't really tell anything sound wise, but when I put my hand over the exhaust I noticed the drivers side felt noticeably cooler than the passenger side. I have no idea if this means anything, it's just a rookies observation.
Any advice on what to look at next? Or even a troubleshooting flow chart type process?
