as stated I have a rough idle in an 85 s15 jimmy 4.3 non vortech at operating temp 100°+. the truck runs fine when it is warming up but once it gets warm it idles like crap and starts running rich. I have checked tps, dist cap+rotor, plugs, wires, egr, timing, and compression all to no avail. I need to get this pos running to sell so I can fund other blazer projects. any help is greatly appreciated.
