Contour Enthusiasts Group Archives Forums General Troubleshooting Low RPM Stumbling, Especially on Cold Mornings

I have a 95 V6 Mtx with 158,000 miles. Lately it has been running rough at lower RPM's. Give it heavy throttle and at ~3000 or so RPM its like turning on a switch and it pulls hard and steady. In the cold, it idles rough and acts rough at low RPM's. It gets better when warmed up, but still doesn't feel really smooth until 3000+ rpm.

Have changed all the plugs (Autolite 764 PP) and had a shop fog clean the air intake system in response .

Before I take this in to the stealership, help me zero in on the most likely culprit.

Thanks,

Chris
