I've been experiencing intermittent stalling, stumbling, and hard start problems for a while now. I've had code for the egr, camshaft sensor, throttle positioning sensor, crankshaft sensor and map sensor, all of which I replaced. It's still stalling randomly so I pulled the harnesses off the ecm or pcm whichever and all four of them have a thick motor oil looking liquid in them, especially the top one! Is this normal? I've also traced several harnesses and plugs for broken wires, haven't found any. Truck runs perfect most of the time! I don't know what else it could be.
