This happened after clearing ice while the engine was warming up. The interitant was on, but the wipers couldn't move. Did I fry something?
Wet weather makes the truck want to idle rough after driving on the highway @ 10 min, next stop causes truck to act as if it has a fuel pump problem(replaced already & filters), putting in neutral keeps it from stalling. Is it Ignition coil, camshaft/crankshaft position sensors, MAF/MAP, brake booster bleed, or fuel pressure regulator problem? I noticed bottom of front carburator's plastic housing small void by something with wires on it, so outside air could get in under the rubber housing gasket.
I know it has somthing to do w/ tranny
transmisson or drive shaft seals
