I think I going to take my manifold to the machine shop and have it checked for warpness and have them shave and straighten it out.

Remember the bolt pattern on the manifolds...and dont tighten one then go to the other....tighten them all at the same pace. Does that make sense?

My problem was cylinder 4 wasnt firing. When I disconneted injector 4 it made no difference thus I narrowed it down to that cylinder. I removed the spark plugs they were fouled with excessive fuel. I was running rich. The intake manifold wasnt sealed good on the the head on cylinder 4 and had a vacuum leak causing the computer to read incorrect. Thus it send more fuel in that cylinder which in turn fouled the sparked plugs.
