I bought a '97 TJ for my son. It has a 4 cyl, 2.5L engine. I have two problems:
1) When you run in 5th gear, it starts sputtering after a while and stops accelerating. If he stops the jeep, turn it off and back on again, he's good to go until next time it happens.
2) The oil pressure gauge drops to 0 when idle sometimes. My guess is the oil pump as we replaced the oil pressure sensor.
Any thoughts will be appreciate. Love the car, but the sputtering is driving us crazy.
