I have a 1995 jaguar xj6 that runs well but begins to idle roughly right before I come to a complete stop and as a result will occasionally die when I come to a complete stop. If I sit there for a moment it returns to normal idle, or if I put it in park it will return to normal idle. It does it hot or cold. There are no check engine lights on, all the coil wires have been replaced, and the MAF, no change.

Can you suggest other possibilities? Thanks.

First eliminate all vacuum or air leaks in the system. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

Thanks you so much. I've got to say I was skeptical about a "free" site offering useful advice but this is amazing, even if it doesn't work. Thanks, you guys/gals are on a mission from God. I'll drop and offering in the plate next time.
