Jet, I did try the working coil from my other car without any difference.

Also worth mentioning is that Brandon had this car for a few days before I ended up with it and he basically tried everything that I did. I did not know this and that's why I proceeded to try fixing the easy stuff.

Yes as you guys remember I did try leaning out the afc that I installed in the car and the misfiring dissappeared. Not only were the o2's low, but I had hellatious counts of knock along with timing retardation as the o2's decreased doing a 1st, 2nd, and 3rd gear pull. That is why I zeroed the afc again as I don't want to ruin the car. The A/F stays pretty solid around 0.90 - 0.92 even when misfiring, so I don't know that it really is too rich or not. I know the best thing to be would have a wideband or dyno it, but this is my daily driver and I don't want to spend that money on it.

The only bit of luck I really had was when I replaced the 3" intake pipe with the stock accordian and hooked up the evap canister hose and valve cover vent hose. At the same time I also put in the cas from my other car. After doing these two things I took it for a drive and the misfiring was nearly completely gone. The only thing I heard were a few lean pops every now and then on the top end. This didn't last more than one run with the car because later that night I went out again and it was beginning to misfire again. That has me stumped...
