mis that gets worse and worse!!!
I have been having this problem with the car. Before I put the cam in it was gradually starting to mis. At first it would mis when I was just cruising but when I would drive it WOT it wouldn't mis at all. Then it started to gradually mis worse and worse while cruising until it finally started to mis bad enough to where I couldn't drive it, and it would mis bad under WOT. I have done a search and could not find anything related... I am wondering if this could be the opti starting to take a dive on me? I now I have pretty large cam and the same problem so bad the car will hardly run.... if anyone could help me that would be awesome! Thanks guys

What have you checked or replaced so far:
-plugs?
-plug wires?
-coil?
-IC Module?
-Opti harness connections for corrosion?
-fuel filter?
-air filter?
-vacuum leaks?
-leaking EGR valve?
-torn inlet air elbow?
-O2 sensors?
-injectors?
Have you checked the fuel pressure?
Have you had it scanned for codes?
does it appear to be running excessively rich?
Who tuned it?

I have brand new plug wires and opti and vaccum leaks.... im gonna change the plugs tonight and the fuel filter. see if thats the culprit. I mean I just put the cam in and before the cam it started this but now its worse with the cam. I also changed the coil about a month ago.

You had an engine that wasn't running right, but installed a cam in it anyway, before figuring out what was wrong?
Who tuned it? That cam is going to run extremely rich at idle and low RPM, unless the person who tuned it knew exactly what he was doing. Good chance its fouling the plugs. Have you checked them?

Fred,didn't you know throwing parts at a car will miraculously FIXX it!
All that was named off by "injuneer" should be checked, scan it bro!
