i was wondering about the distributor.....i guess they COULD have put it in 180 degrees wrong. ill take a quick look. it was aa previous b18 in the car. the b18 started smoking. the motor in it NOW replaced the one that was smoking. it was put back together, and im only asumming they got all the sensors right. i guess i need to use a scanner, the whole cars been converted to obd2. i DO have a check engine light.
