I have a 1990 mighty max I bought off my neighbor he was tired of sinking money into it and got it fairly cheap so figured why not.
pretty sure the plug wires are new as well(might just go buy some to see if thats possibly a issue
fuel filter under the truck looks pretty new as well
runs rich so rich it left black on my carport and plugs black as can be when I took another look at them they are only three weeks old
Idles rough,has a miss
bucks at low rpms when accelerating I would say 1000-1200 rpms(no tach)
I have taken a look at the vacuum lines they look like they are correct but the diagram was a tad bit confusing that I found anyone possibly have a link?
No check engine light which is odd to me usually with my old 1991 s10 it would throw a cel when anything was wrong
any help would be appreciated I just dont really know much about these trucks. I have looked around the forum but not really found much
