Throttle Position Sensor / tranny jolt

[baron1701]

I just wanted to share a positive Aurora experience. For the two years I have owned the car I have learned a great deal but there was one thing I couldn't figure out. When I bought it, I got it at a dealer auction for $2,200 in impecible shape. Or so I thought. I didn't know squat about anything other than my older Lincolns and Mercury's, I thought that the car had the bulletproof 3.8L and 4t60e Trans. Well I did get fairly lucky but I had to rebuilt the tranny and some work on the engine accesories and wheel bearings. I always had a problem, even after the rebuild, in traffic where if the idle was allowed to drop bellow 1k rpms it would plummet to 500 rpms instead of hovering at 750 for a time. This created a very bad jolt to the mounts and such. Well I took a shot and replaced the TPS and now it seems fine. A $30 part made my car that much better.
