Rough Idle quad 4...


Recommended Posts

Posted

My 90 International started having some rough idle issues this week as well as loss of power. Checked the module to see if that was it and changed the coils.. problem was still there. Weird thing is it only does it when its warm. If i start it up cold it will run forever fine. but when i turn it off and start it, it runs rough. Pulled my plugs and they were fine also had the module checked at autozone and they said it was fine. I dont really wanna mess with it a whole lot. No oil in the coolant and no coolant in the oil. Any ideas?

 

Forgot to say once it starts ideling rough it runs that way until it cools down completely.. takes about 4 hours. And acceleration is non existant. It boggs so bad you pretty much cant even drive it.

If you haven't done so already, get your ignition coils checked. This is probably a long shot but worth looking into. When I had my Quad4, the coils went bad and it would severly bog on acceleration when the engine was up to temp.
