I've got a '92 pickup with a 22re. The past couple of days it's been idling really rough, to the point of almost stalling. It also bogs down when acclerating till about mid way through the rpm range(just guessing because there's no tach) then it clears up and the top end pwoer is actually pretty good. I thought it might have been the plugs, wires, rotor and cap because they were pretty bad shape but that has not solved the problem. I'm woundering now if it might be the O2 sensor? Any other thought on what it could be?
Thanks
Adam
