Car never idled well since i put the motor in. It ran pretty good but will die every so often. Now the car dies everytime i hit the clutch. I unplugged the o2 and it runs exactly the same. I have a circuit tester with a light and it shows the wiring is sending signal to the o2. Should i just replace the o2 and see where im at? Could it be possible this is the reason why my cars never idled good for the past 3 months? Also the cars has just recently been randomly bogging for about a week. Its like a crazy misfire, it doesnt do it at only high rpms or only low. It just does it randomly. Could this all just be o2 related?
