o2's making the engine run rough, do i need tuning?
well it was running smooth and nice w/out the o2's in, i was just getting bad gas mileage. Today i installed the o2's, reset the pcm and the engine runs extremely horrible. i tried driving it a few miles hoping the pcm would start tuning it self to the o2's but nothing happend, kept running horrible
i plugged my OBD reader in, and the o2's are showing normal readings
any thoughts?
