- 2003 Ford Ranger 2wd 3.0
I have a 2003 Ranger 3.0 2WD with a rough idle when first started. It comes alive once the fuel trims adjust up. They are in the +50 range. I've smoke tested the intake, tried plugging all vacuum ports off, and nothing changes it. Replaced o2 sensors, intake gaskets. As far as im concerned there is no possibility of a vacuum leak. The fuel trims stay extremely high, even when ran at 2500 rpm. The next step in alldata is to refer to the PC/ED. Anyone have any ideas? Injectors? PCM?
