Vibration at about 2000 RPM

I've done a search, but couldn't find a related thread.

After the last trip to the dealer for a gas leak, I now noticed a vibration under load (like starting from a dead start) at around 1800 - 2000 rpm. I don't think it was there before - so I'd have to say it was new? At first I thought it might have been some bad/old gas - but I ran well into the low fuel warning light and filled up with unleaded premium and put on a few hundred miles to clean things out.

I don't feel the vibration anywhere else in the engine RPM range - and cruising at 65mph in 5 or 6th seems normal.

I thought maybe they disrupted a throttle linkage, damaged a spark plug wire , fowled a spark plug. So before I head back to the dealer, I need some insight/recommendations from the 'Forum'.

Any Ideas?

Make sure the throttle cables are properly seated in the metal ferrules- they are very easy to dislodge when work has been done.

Thanks for the advice - we will be sure they are seated correctly.

You may be in need of the old fashioned "Valve adjustment and Throttle Body Synchronization".
