89 F-150 Problem
I have just had a bolt removed from my pass. side exhaust manifold that had snapped off. I removed the intake, and the head to have it machined out. Replaced all the gaskets. Everything looks fine. When I start the truck up the oil pressure goes to normal. If I put it in gear, it drops out completely. If I give it gas it goes right back up to normal. It almost wants to stall out when I put it into gear or come to a stop light. I replaced the gauge sender. I had it hooked up to a computer it reads clear. I had a compression test done on every cylinder it reads like the truck is new. I let the truck idle in park and it sounds fine no knocking from no oil. It is a little rough on start-up. But it eventually it smoothes out. What could it be. The gauge itself? Idle motor? Like I said I have done EVERY computer test on this thing and come up with nothing! PLEASE HELP!!
