Has anyone else experienced a problem where the vehicle does not return to a normal idle while rolling out of gear?
Just in the last few days, when I push in the clutch (Like slowing to a stop) and/or take the car out of gear, instead of returning to the normal ~700rpm, the engine stays at 1100-1200, and slowly increases rpm to about 1900, then drops back down to 1100 and repeats? Its almost like 'breathing' is the best way to describe it.
The odd part is, when the vehicle is not rolling, it returns to a perfect 700rpm idle.
Some information that may be relevant: I did allow the vehicle to warm up before driving, so the idle was around 700 before starting to drive. Ambient temperatures have been upper 30's and extremely wet and rainy these past few days.
I'm K-tuned on the base map, with the PRL Race MAF scaling option for the Cobra with Race MAF. Otherwise the car is bone stock, and I made no changes to the tune itself.
Haven't had a chance to drive around with my laptop and get some datalogging yet, as I have the Ktuner V1.2, but using the android app I checked my fuel trims, which are perfectly normal, and my knock control doesn't stray from .49 as I'm running 93 octane.
Any suggestions on where to start troubleshooting, or a specific parameter in the datalogging that would give away a mechanical or a tuning issue? Any advice is appreciated.
