Tried to find something from the search button, but couldn't find what i was looking for...

so here is a short story (shotened it as much as i can)
came home parked in garage, got back in my car less than 20 minutes, start the car, engine is shaking in low rpm between 500 and 750 in parking gear but doesn't die. i needed to back out from garage, so i put it in reverse, same shake, so i put in d5, same shake, but engine still is alive. i reved a little and it goes back down into low rpm. i drove for about 2 blocks, car was back to normal...
any ideas?
car info:
114,xxx miles
2000 TL A/Trans
replaced tranny by last owner when car had about 80,xxx miles...

 

Unless it continues to do it i wouldnt worry about it.

 

sounds like a dirty IACV. I've been having this problem too. try cleaning it out
