I have a 1994 XJ with 140K miles. At idle after the vehile has warmed up the engine will miss perirodicaly while I am ideling at a stop light. Occasionaly, when taking off from idel the vehicle will hesitate slightly. Every thing seems to be fine at higher RPMs and the gas mileage is still consitent.
I think it might be the fuel pump. I replaced the fuel filter and there was black residue coming out of it.
First, could it be the fuel pump? (it is the orginal fuel pump)
If it is the fule pump, how can I tell whether it is the short or long fuel pump?
Tell me what you think.
Anything will be helpful at his point.
Thank You,
