Hi all,
My 2004 Sable DOHC V6 has been running rough after it warms up. The problem is intermittent and acts like a bad coil or plug. During an outing, the car will be fine until the engine warms up. Then it starts sputtering (missing) off and on, both while idling and driving. Will be fine then start acting up again. No codes related to this are showing, no chk engine lite. I replaced all the plugs and one of the COP coils last August when I had a similar issue. Then I finally, after many days, got mis-fire code for #6.
Now, today when I was driving and the engine was missing badly, I turned off the AC. The engine immediately quit missing. After I got home, I noticed that the missing happens when the engine is warmed up and the AC is on. When I turn off the AC it runs fine. Anybody run across this before?
Any ideas will be greatly appreciated.
Bob
