Got a rough run problem

[fallout]

I have a slight misfire, not too bad but there is def. a pulsing sound to it. And in first gear and first gear only when I give it WOT it goes to 4100rpm and hits what sounds like a fuel cut, but just wont rev any farther. The tach pretty much stays at 4100rpm and just bounces like a rev limiter, but it definetely isnt the tranny slipping. If I let it shift to second and speed up a little, then give it WOT it will shift to 1st and run to redline just fine, like it always should. I have an o2 sensor out for the moment with a plug in the bung for it until I can get a new one. Is that what is causing the first gear problem? I can only think that it would be some kind of electronic nanny keeping it from going to redline in lieu of the missing o2 sensor. Can anyone help me?

Bad coil. With one completely dead the car runs like dog sh*t.

Take it to Autozone and have them pull codes. Although you have to be pretty lucky for it to kick out a miss fire code. Could be a IMRC problem too I suppose now that I think about it.

Well I just got back and the thing had codes for the o2 densor (go figure I knew that one), something to do with the MAF, a cylinder #3 misfire, and a few o2 sensor ones.
