Please help!! I have 1999 cherokee 2wd 4.0l. The problems are this, when you first go out to start the jeep for the day it takes 3-4 tries before it finally cranks up and runs. It turns over fine just does not crank up. Once it crank its fine an will crank first try everytime until you let it sit for 3-4 hours or more. Then once you have it cranked it runs fine except for if you let off the gas quickly it will stall when you come to a stop. If cranks right back up but I you give it gas and let off again real quick it will die again. The other symptom is when your driving at normal speed and you try accelerate hard or quickly it will sputter several times as if its about to die but if you keep the pedal down it smooths out and will take off and go till you let off. The jeep was giving a tps code and a camshaft position sensor code. I replaced those and the crankshaft position sensor and still nothing. It also has a new aic and plugs and wires cap, etc. please help.
