i did a motor wape with my car a while back . i recently had a bad timing belt had took it to my pop's friends to get it replace. biggest mistake i ever done . should have just did it my self . he mess around with all the wire'n . he cross wire my iat sensor with a 12v and burt it out and some out blew out my map sensor . i replace everything that needed to be fixed . after replace the obd1 map sensor . the check engine still tells me that the map is not working correctly . why would the obd1 code still blink 3 (map sensor) if i just installed a new one ?
