walters Posted April 24, 2007 Share Posted April 24, 2007 This code says there is a fuel trim malfunction on bank 1. Replaced o2 sensors on this bank not long ago, which took care of another code. Bit this one remains. Took apart maf and cleaned and replaced air filter. I am open for other suggestions. Quote Link to comment Share on other sites More sharing options...

LScott400 Posted April 25, 2007 Share Posted April 25, 2007 From what I can find either a faulty MAF or a vacuum leak are most likely. Quote Link to comment Share on other sites More sharing options...
