Early 95 PSD Hard Start, Rough Idle, Runs Rough, Dies When Warm
A quick overview of the truck.
Early 95, 4x4 Manual with 185k miles
The truck will start after several cranks and usually have to lightly tap the accelerator before it fires. Once it's started it has a rough idle that obviously 1 or more cylinders are not firing. Eventually the truck will idle on it's own without having to keep it around 750 RPM. After running for about 10 minutes it shuts off like I turned the key off. After sitting for 30 min to an hour, it will fire back up, still running badly. No black, blue or white smoke while running. After several starts or if it runs for at least a minute, it starts again much easier than the first time. But never runs smoothly, always missing.
What's been replaced
-IPR (can't guarantee it has the edge filter like it should)
-pigtail to UVCH driver side
-checked & unplugged ICP sensor
-have not put it on AE to check contribution or do a buzz test
I'm at a guess that it is either O-rings or injectors. Anybody had similar issues?
