Hi. My 3.2 diesel 4m41 runs great but it's like it has a cough. It sometimes misfires. Sometimes once. Sometimes a few times. Can get bad at idle. Stalled a few times. Happens at higher speeds to and disengaged cruise control. Cleaned out inlet manifold and still the same. Noone has heard of this before. Any ideas?
Thanks. 3 mechanics have worked on it so far. All those things have been checked. They are now suggesting a computer failure or chemical clean of induction manifold and system
Next time please describe everything that was already done in your question. Our time is valuable too. Thanks
Fixed it!
How? What was the magic potion?
