my 01 jeep grand cherokee laredo is misfiring. My mechanic replaced the ignition coil and…
The problem started when turning right. The engine would cut out like it was out of gas. Sometimes it would die, but start right back up. Now its happening just driving down the road. We changed the fuel filter, that did not help. Don’t know what to check now?
90% certain it is the ignition control module. This is a common failure part for this model.
Ignition Control Module Replacement
- Remove the distributor cap and rotor.
- Disconnect the harness connector and pick-up coil spade connectors from the module. Be careful not to damage the wires when removing the connector.
- Remove the two screws and module from the distributor housing.
- Coat the bottom of the new module with dielectric silicone lubricant. This is usually supplied with the new module. Reverse the above procedure to install.
1991–98 Jeep vehicles are not equipped with an ignition control module. However, the functions of the ignition control module are performed by the Electronic Control Unit (ECU), also known as the Powertrain Control Module (PCM).
