Once the car is completely warmed up, the vibration is pretty bad at a complete stop. It seems to be primarily focused up through the steering column. Because of age and suggestions from many others, all motor mounts were changed, we also increased the idle. Did the first 3 mounts and did not do the last one because the mount looked fine. The vibration improved, so we decided to do the last one. This has now made it even worse. Increasing the idle helped some, but when you add any load, it bogs down. Going from Park/Neutral to drive, it drops. Add in turning on the lights, it drops more. Turn the wipers on and drops even more. Tested the battery and alternator and both tested fine. Need suggestions.
