Hoping you guys can help me out...
Have an '87 Ranger 4x4 with 2.9 MT.
It's never run all that well. When I first got it, I put in new plugs, wires, cap, rotor and pickup. Drove it most of the winter.
Few months ago, it would occasionally stumble at low RPMs and then suddenly recover.
Pulled the codes, had 31 and 32. Replaced the EGR valve.
Drove it a few months more till the weather improved.
Earlier this week, pulled the codes again. 31, 32 and 41. Replaced the EGR solenoid valve and the EGR sensor. Ran a vacuum to the EGR valve while idling and the engine died. Also replaced the coil.
Now with the engine off test I get 11 for current and 32 for history.
When running, I get 22, 41, 32 and 25. It idles really awful now. This is without the brake vacuum line plugged (see below) - I'm going to go plug it and test it again while running to see if that affects the 22 and 41 at all.
When I ran it around the block to heat it up before testing this last time, I noticed hissing when applying the brakes and the brakes don't have much assist all of a sudden. I think the vacuum assist diaphragm is probably leaking. Plugged off that vacuum line, but the idle still sucks. Will occasionally stall at a stop and is very hesitant from a start unless you wind up the RPMs and then it's fine.
I'll post back in a few when I test again with the vacuum line plugged off, but I suspect that 32 will at least be there.
Anything else I should be checking?
