OK, I know this is GM, but I also know we have some very good gearheads here that work on other brands as well.
My 1990 F150 is getting on my last nerve. It will stall out. Some times when driving, others when not moving. When driving it will clear out and go again because I leave the clutch out. But when not moving it will die. This video shows what happens.
I've already replaced everything on the ignition system, so that'* not it. It'* not fuel, because it'* flooding. Today I had a little extra time so I pulled it in the shop, it stalled 3 times. So I hooked up just about everything I had to monitor the engine next time it stalls. And, it runs for 20 mins with out a problem.
At this point I have 2 ideas. One, a clogged cat. But I don't have a vacuum tester, if I did I could test that. The other is the EGR valve. When it ran the long time I had forgotten I unplugged the EGR. But that'* $87 and I'm not changing that on the off chance that'* it. I'll just unplug it. Thoughts? Ideas?
