I have noticed that when the outside temperature is cool, it does not happen as much. I have been told it could in the EGR system or something to do with ignition timing. From what I understand, the ignition timing is controlled by the ECM and cannot be adjusted. Is this correct? Can someone give me some guidance on what I can try next?
have the same problem?
