I picked up the gas from a new place for me, but it is a pretty well known place around here.

If it was the alternator how come the engine is stalling out before I loose radio everything else. When my alt. went before I lost everything lights/dash/radio but the truck would keep running. I guess it was getting just enough power for the plugs from the battery.

Where exactly do I spray the WD40 when checking for a bad intake manifold?

Thanks Again
