Ok guys im at my wits end short of taking a match to her and watching her burn while I roast hot dogs I cant figure out this problem...... I have a 97 with 4.3l I have changed fuelpump, plugs, wires, cap, rotor, maf, crank pos sensor, air filter, and im still getting a cylinder 6 misfire I took it to a place and they hooked it up to a genesis machine and he said the crank sensor and maf were bad so I changed them and it is still idling rough any thoughts
