Gregmatic Posted February 28, 2010 Share Posted February 28, 2010 Short answer: yes You'll need to do a minor repinning of the O2 sensor wires but otherwise it should work fine. Earlier (84/85) ECU's are known to have a rough idle when initially started and the motor is cold, fine when they warm up. Quote Link to comment Share on other sites More sharing options...
