The One millionth question on Check Engine Lights
Hey there!
Have a gee whiz for you all. My stang the last two weeks has been throwing a CEL for P0172 and 0175 saying the banks are running rich. Now the thing is it tends to do it after it has sat for awhile or is cold. It has done it while warm, but seems more often when cold. Any suggestions? I am thinking fuel pump. Plugs are good, filter is changed, even backed off 3lbs of fuel pressure on my regulator. Kind of stuck to where to check next. The MAF sensor was cleaned with Electrical Contact Spray and looks good there also.
Thanks!
