1996 contour code 171 system too lean
have a 1996 contour
engine light keeps coming on, got a reader and code 0171 is popping up
System too lean (Bank 1)
about 70000 miles on it.....if anyone can give me a few clues where to start it would sure be
also hear like a loud rattle usually when first started.....looks like a cover for the timing chain??? rattle appears to come from there
doubt the 2 things are related?????
