Ok. I'm having some trouble determining what is going on after I've driven the car for a while then place it in park.
I get 1-2 seconds of shudder, followed by the same of smooth idle. If the same thing happened while stopped at a light, I might think it was idle speed/fuel delivery related (and it may still be). And occasionally after a spirited run, the engine will shake pretty good when I come to a stop, but smooth out pretty quickly.
But when I put the car in park it's a very quick shudder without much rocking like I get when I just stop in drive.
Any thoughts?
