I've had a misfire for awhile now on my 97' tah. It hasn't been driven much at all lately.. Had scan tool put on it long time ago.. had crankcase cam relation code.. replaced both of them.. still had code for a long time after.. started mis firing AFTER them were even replaced.. Had code checked again recently... got a O2 code. Guy forgot what O2 lol. I tried cranking off one of my upstream ones on drivers side.. couldn't get it off for the life of me. I unlplugged it, plugged it back in, tried it some more,finally gave up. Start Her up, misfire is twice as worse now, even killed on me when put into drive. Misfire is WAY worse when put into a gear; but still really noticeable when in park. When I put it in drive the lights were dimming with the idle, oil pressure gauge was fluctuating with it. Why did it get 2x worse? Do you really think it could be a O2? Body has about 168,000. Motor was replaced like 4 years ago I think. I've had a Fuel Pressure regulator put in. A buddy I know thinks it could be the distributor being off when the mechanic put it back in, causing the misfire. But the misfire didn't come about till way after that was replaced. Thanks guys-
