Rough Idle after a few hard street runs.


Recommended Posts

In addition to my previous post, I'm also in need of some info as to why I would get a rough idle after I run the car hard thru the gears. There is no stalling or performance loss. Mostly noticed from idle up to 2000 RMP when taking it slow around town, almost feels like it's hesitating and bucking a bit. Once you shut it down for an hour or so, it's fine, but will repeat after another hard run. Any input would be appreciated. One other bit of info, I never ran it as hard and or as long as I did today. Could this be an ECM relearning process? The 2012 SVTPP Conv. is 100% OEM.
