Hello. I have a 2002 Jaguar S-Type 6 cyl. with some idle issues.
The 1st issue is that the idle is slightly dipping up and down whenever the car is at rest . The fluctuations in idle are often minute but still noticeable...often running between 700-900 rpms.
The 2nd issue is that my idle is running high after acceleration. This problem began after I replaced the sparks and coils on two cylinders that were misfiring last week. At the same time, I also cleaned out the carbon from the throttle body.
Whenever I accelerate to any speed and then let off the gas pedal, the idle hovers around 1500 for 20 -30 seconds before returning to normal. Also, sometimes the idle pops high as I begin to come to a stop from higher speeds.
Thanks for all the help!
