Question About Idle
Many times, when I decelerate and then push the clutch in, the engine speed drops to around 600 rpm, then goes up to around 800 rpm, then back to 600 and remains there. Is this a normal function of the engine management system or something I need to get checked at the dealer (still under warranty)?
Thanks.
John

This may be normal. The best way to check is with a Tech 2 and compare the actual idle RPM to the command idle RPM.
When you depress the clutch pedal on decel, there may be a lag time before the ECM can adjust the actual idle speed to the desired idle speed.
