Question about 2000 Jeep Grand Cherokee
I have a 2000 Jeep Grand Cherokee. Engine rough at Idle and exhibits lack of power and stumbles at about 45 mph.
Scanner Freeze Rame Data ( At Idle )
Load % : 16
MAP KPA: 41
Coolent Temp: 114
ST FTRM1( % ): 26.5
LT FTRM1 ( % ): 32.0
ST FTRM3:( % ): -2.2
LT FTRM3 ( % ) : -52.2
Fuel System: Closed
Replaced fuel filter/regulator, replace 02 sensors, replaced vacuum hoses and fittings, incl. EGR fittings at valve conver. Replaced IAT sensor. Checked MAP sensor, throttle position sensor and idle sensor voltages with VOM meter - all OK. Checked fuel perssure - OK. Removed and cleaned throttle body. Removed and cleaned spark plugs. Should I be focusing on fuel related problem or vacuum related problem. Change fuel injectors ? I'm beginning to suspect water in fuel. I would appreciate your help.
Check PCV valve and be sure it is not stuck open. Check for vacuum leak at intake manifold.
