JOHNBIGDOG Posted February 9, 2013 Share Posted February 9, 2013 The actual "P" code would be nice. Quote Link to comment Share on other sites More sharing options...
Jeremy airjer W Posted February 9, 2013 Share Posted February 9, 2013 Agreed! The code is a letter "P" followed by four numbers (example, P0128). Quote Link to comment Share on other sites More sharing options...
CAMAN Posted February 9, 2013 Author Share Posted February 9, 2013 They didn't give me a number. Just said it was a low idle fault, then cleared it. *edit* Just Google'd it and sounds like a common issue with these trucks with over 100k. Cleaning the MAF sensor and throttle body should fix it. A little Carb cleaner and a toothbrush. I like these kinds of fixes. Quote Link to comment Share on other sites More sharing options...
JOHNBIGDOG Posted February 9, 2013 Share Posted February 9, 2013 Ibwould notbuse either one of those items. CRF make a maf cleaner use this product. And if anything a q tip to clean the sensor elements. Quote Link to comment Share on other sites More sharing options...
Jeremy airjer W Posted February 10, 2013 Share Posted February 10, 2013 I would not use carb spray to clean the MAF as well. Quote Link to comment Share on other sites More sharing options...
