spark? fuel?
Look on the back on the transfer case. There should be one wire running from it. That's your speed sensor. -- Blake.
check for spark and fuel pressure I just had this problem with a 1989 Cherokee and had to have a Cranking Sensor installed.
There is no afs on a cherokee, they run on a map sensor.
You might look at the o2 sensor or the temperature sender
i changed plugs wires throttle p sensor an checked fuel
There is no knock sensor on a 94 4L jeep engine. In 1991 when they changed to the 4L HO motor, they removed the knock sensor from the system.
The Oxygen Sensor on a 1989 Cherokee 4.0L is on the exhaust pipe on the left side of the engine just below the exhaust manifold. You can see it from above but you must replace it from below. It is pretty easy to reach. I recently changed mine and it took only 10 minutes using an O2 sensor wrench.
A 1998 Jeep Cherokee does not have a mass airflow sensor. It uses a manifold pressure sensor, MAP, which is on the rear of the intake manifold.
Your O2 sensor is a "part that is designed to wear out". there is no standard on replacing them, but if your car is running fine, and your check engine light comes on, and stays on, it's probably an O2 sensor.
Try replacing the camshaft sensor. Sounds exactly like the problem I experienced.
The cam sensor is in the distributor.
The sensor is not adjustable.
