High Idle

Hi,
Does anyone know if it's possible for the dealer to go into the ECU and adjust the in gear idle ? My 03 str is pulling a little hard in drive when I have the brakes on and when I take it out of gear the idle jumps up about 150 rpm before it goes back down to rest at about 650 rpm. does anyone else have this issue?
Thanks

RE: High Idle

most likely you have a sticking idle air control motor. or your entire electronic throttle body is taking a **** on you.

RE: High Idle

Is the idle air control motor something that I can get access to myself and check it out?

RE: High Idle

There are no servicable parts on the E-throttle and it is sooo expensive, its not worth it to just guess. I am a Master tech for jag and porsche, so I always test and it doesnt hurt to have the right technical info at hand to diagnose, such as having the factory scan tool, wire diag, Tsbs LAb scope
ect. Id go to a good shop thats capable of diagnosing a Jaguar, since this is not a common car. Or go to your dealer and have the shop foreman diagnose the problem.

RE: High Idle

Thanks, I'll do that! I have brought it to their attention several times but no luck. I wouldn't mind so much if the car didn't want to pull so hard when I put it in drive and reverse and when I come to a stop. If I let off of the brake It will go up to 6 + mph right away and when I stop it shifts into first just as I'm about to stop and causes it to jerk forward. It really moves fast in reverse! Is it possible for them to simply adjust the in gear idle thru the ECU or the TCU? They tell me that there are no codes showing up but this didn't start happening until after ther did a hard reset of both.

RE: High Idle

There is no idle adjustment feature on the factory scan tool, so no. This problem needs in depth diagnsosis by someone who likes to takle hard problems, but its hard to find a tech who is like this. Good luck.[&:]
