I have a 98 lude with H22A4 and the steptronic trans. When you are driving around and stop and put in park the ide goes up to 1500 and back to 800 until you put it into a gear. Does not do this while in gear.

Also has anyone have any problems with the speedometer. Mine seems to be off about 10 MPH. Is this an electrical or mechanical issue?

 

i have the same problem. i posted it up, but i got a few responses.
