My 2000 is doing the exact same thing. Pulled CPS code, swapped that with OEM part, (aftermarket sensors are junk).....no fix. Pulled coil pack code, swapped a buddies in from know well running same Jeep......no fix. Fuel pressure at rail about 47...so good there. Changed plugs while at it....no fix. Still scratching my head and trying to figure this thing out. been told to check ground wires and motor and tcase mounts....watching this thread for some answers....
