Question about 1993 Jeep Grand Cherokee
Upon idle it shutters however when driving it is fine, then when coming to a stop it starts to idle roughly again! PLEASE HELP!
Also check the vaccum hose from the fuel pressure regulator to the intake manifold, it is right on top, to the front right of the valve cover where the fuel lines attach to the fuel rail, there is a small vaccum hose that runs from the regulator to the intake manifold, I have a 93 grand cherokee limited w/ 4.0L 6cyl, it was hard to start at times, wouldnt start at times without starting fluid spray and had your symptoms at idle, running rough like it wanted to stall like it was out of gas, I had various opinions ranging from fuel pump was bad to the fuel filter to the fuel presure regulator, the fuel pump relay ,etc....after replacing the relay and having the same symptoms, some digging brought me to this vaccum hose, wich had a break in it, when it was replaced it allowed the regulator to have the correct fuel pressure output and solved all the afforementioned problems way cheaper than the suggested alternitives. good luck.
