Engine Stumbing/Hesitating
Hi guys. My 02 S80 T6 has developed a slight, intermittent "hesitation" (or miss?) shortly after cold start (one minute or so) and remains until it has warmed up. I notice it when I stop and idle - I can feel the engine stumbling a little. It doesthis in all gears, park and neutral. Acceleration is rough also but seems better after warm up. Would this bea coil pack starting to go?
Thanks, George |

Could be a coil pack any check engine light?

No check engine light at first but then eventually it came on intermittently and now has latched on. No messages though. I don't see any evidence of a spark plug change in the service history. It has 180,000 km - I should probably change them.

Find out what codes are in the system. That would lead to which cylinder it is.
