I just gave my truck a good tune-up to fix what I thought was an exposed coil or broken cap, but it turns out it still starts to "pop" out of the tail pipe and shake at idle when it rains. Off idle the engine runs really well for a carburated(4brrl) 1986 4.3L. (there is so much emissions crap on this thing)
It also ran really crappy when it was real cold out too (30-40°F)
Oh yeah, here's another thing: There is always oil in my enclosed air cleaner area. The breather gets gunked up a few days after i put a new one it, the PCV valve is functional(when i take it out and shake it, it rattles). That's another reason, the emissons crap pisses me off, so many hoses going everywhere to all these sensors and probably only half of them work.
Any ideas? I guess I should make sure all the HEI ignition wires behind the distributor are sealed from the elements.... I just thought it might be carburator related. I had the carb "rebuild" be a speed shop in Langhorn PA, but I never realy did anything as far as carb tuning, because I actually DON'T know anything about carb tuning...
thanks for listening
so far: new coil, cap, rotor, wires, fuel filter. next will be, valve seals, spark plugs, and some chevron engine deposit cleaner.
