Ok, so I finally decided to replace my exhaust manifold because there was a big crack in one of the welds and it was starting to sound pretty bad. I got the new manifold in and spent all day replacing it.
Just tried to start it up and the RPM shoot way up so fast that I just hurry up and shut it off. I know that If I did not get the Intake manifold on perfectly that the engine will not be able to draw a vacuum and that will cause the RPMs to go up, but I totally checked the placement (I thought) like multiple times to make sure it was attached properly.
I am very frustrated and before I totally dismantle this thing again to basically start over, I wanted to defer to the infinite wisdom of all the Jeepers on this forum.....
Does anyone know of anything else I may have screwed up or maybe need to do, before I totally redo this job......ugh.
Its a 4.0L engine, and I bought that new style manifold with the bellows for expansion that will supposedly work better.
