i put on denso o2'*, alot of people recomended them. the car didnt actually start dying until after i changed the o2'*, it was just stumbling/jerking before. i actually pulled out the MAF and the little wire with the diode was intact.
the o2s looked like they needed to be changed, especially the upper. it had a bunch of crap on it, probly from when my coolant was being burned when my LIM failed. but when i changed them, the code didnt go away and it started dying. im thinking its something before the o2'* thats either making it misfire or mess up the mixture.
