Could this be normal or just one of the flaws in this engine design. It's real annoying that this engine cannot idle smooth. Any suggestions.
I have a similar problem and the dealer says no error codes are being recorded, but they have felt the "missing" while sitting in the car... Someone else had a problem as well and they said the dealer re-flashed the ECU and that there was a TSB on the problem, but I have not been able to find a TSB, nor has the dealer... Let me know what you find out... maybe DFWBR can help since he works for DC
