Still trying to track down a P0171/174. Can't find a vacuum leak anywhere, have replaced EVERYTHING (MAF, Both O2, plenum gaskets etc) that it "could" be. Just ran a voltmeter test.
According to the manual, probing the SIG wire with the ignition on but engine off should read 400-450 millivolts. I get a reading of 337 millivolts... don't know where to go from here but could this be a start?
