djspawn00 Posted March 14, 2007 Share Posted March 14, 2007 I think you may have needed an A/F ratio sensor which is like an oxygen sensor but a lot more expensive. Quote Link to comment Share on other sites More sharing options...
justin97 Posted March 14, 2007 Author Share Posted March 14, 2007 well 122. each for them, not expensive engouh? well i finally went and replaced both the back one had gotten into an aruge ment with the exhaust manifold and meilted the connector. that was my problem. another question there is a sensor on top of the power steering pulley assembily. how important is that? what would happen if if broke and was not fixed?
