Ran well before changing motor mounts. Starts quickly and rpms jump to 1,500 rpm then settle at 1,00 for a few seconds before dropping to around 550 rpm,(where the idle is rough and causing vibrations)Off idle, jeep seems to run well. Rough idle only occurs when stopped. If I am driving down the road and allow the jeep to slow to idle, it will maintain 1,000 rpms and idle smoothly. When stopped, the idle drop to 500-6-- rpm and is rough. THis i true even if I stop using only the ebrake. Idle is rough in any gear, foot on or off the brake.
Ive inspected the vacuum lines and elec. connectors extensively. No stored codes. Cant find any vacuum leaks using throttle body cleaner or propane. I have a vacuum gauge but am not trained at interrupting it.
