update on my situation. I did the ohms continuity test. GP's 3,4 and 5 have <1 ohms resistance (0.7 or so). I guess that is good. GP 1 has 26.5ohms and GP2 has 13.6 ohms resistance. I guess that is not good. Is that my problem, GP's 1 and 2 are bad? Still I am not completely comfortable that the light is coming on after it is started. It stays on for ~45 secs or so. If anyone has a detailed description (with pictures) on the intake manifold removal I would appreciate it. My worries are what to do with all the crap that hangs on top and on the side of the manifold. Will it move once the bolts are taken out or do I have to remove a bunch of other stuff. I'm hell bent I'm going to do this but timid that I don't screw something up.
