My 95 XE 4x4 has been misfiring for some time now. Stuttering and shuttering during acceleration and has a pretty consistent misfire at idle.
It has codes for EGR function and Knock Sensor.
I've replaced the plugs/wires, ignition coil, distributor cap and rotor, and fuel filter.
The shaft on the distributor has some play in it so I'm wondering if this could be contributing to the issue?
I've disconnected the O2 sensor to see if that would help and it made no change to the issue.
The mass air sensor has been cleaned but is the original part in the vehicle.
The tac bounces up and down from 500 to 1000 rpm depending on the load on the motor.
I just ordered a new mass air flow sensor in hopes that will fix the problem.
Does anyone have any other suggestions as to what I can try to alleviate the issue?
Thanks in advance!
