Question about 1988 GMC S-15
This only happens when weather is both wet and cold.Have replaced cap&rotor,oxy &throttle posit sensor,plug wires,oil relay,fuel filter,map sensor,pcm,egr. checked and cleaned all connections i can find.Something seems to be telling it to stop sending fuel.Runs fine while spraying aerosol into tbi until the can runs out.Runs about 10 seconds till it dies. Over and over again. Diagnostic machine claims there are no issues. If brought inside for a few hours it will start and run fine. Please help. Thanx.
