Hi guys I'm sort of lost as what my issue could be. First I'll start with what's going on and I apologize for the lengthiness but just keeping from you having to ask for the basic stuff. My car (99 Regal GS) was left at home and driven very little for a week. The parents got the oil changed while I was gone also. Other than that there was nothing done to the car except the sway bar bushings were greased up a bit.
So I get the car back, no CES, no service vehicle light, and drive it back home with no issues til I get to the first light off the interstate when I have to come to a complete stop. The car starts vibrating as people describe when you get all poly mounts (uppers round and square, tranny, and engine) and it suprised me because why would I suddenly get it now after installing just the upper square ones almost 4 to 5 months ago? To clarify, its like sitting in a vibrating back massaging seat with the dash vibrating right along also. The engine sounds fine; no misfire, no strange gurgling or high/low idle, and when I'm at a complete stop and raise the idle what looks like maybe to 800rpm it goes away. Also to note, I believe I have some sort of power steering issue/magnasteer of some sort also. I recognized that when turning the wheel at a stop in overdrive the vibration goes away but when I leave the steering wheel turned the vibration is slightly more noticeable. I checked the fluid today and it was low so I'll take care of that tomorrow.
One more thing to note when I got home and parked the car, when I was shifting it between gears, when going into reverse there was the sound of rattling parts or something.
I have no idea if all these issues are connected or what but just a week ago I was having only noticeable harder to turn the steering wheel issue. Now after the oil change and getting it back all these things have come about.
Any ideas???
