thats basically what was done. everything on the head is obd2, besides the head itself. I knew the guy was a jerkoff. its funny how little some mechanics know when they dont have a book or instruction manual in front of them. so anyways, car still throwing codes although cant check cus I lost my manual. can someone tell me how to rewire the crank angle sensor to connect the one on the obd1 distributor to the 99 harness, because a friend said that is most likely messing shit up. any and all feedback is appreciated.
