robstacles 1 Posted June 2, 2017 Share Posted June 2, 2017 My Spark still behaves erratic at times and I have never been able to find a surefire way to replicate the issue. Even if the TCM, ECM, and PCM says it's the current version, would a reset help? Do dealerships perform software reprogramming or resetting on request? Link to post Share on other sites
Retired old Gearhead 201 Posted June 3, 2017 Share Posted June 3, 2017 Certainly worth looking into Rob..Try to come up with a specific list for them. If that approach fails find or go to your trusted mechanic and spill the details trying to be as accurate as you can..Not sure if a reset is necessary and not all issues are electronic, however the ECM does control quite a few functions. Always remember to bring notes as detailed as possible since intermittent issues are always difficult to pinpoint without some details as a starting point to use a process of elimination to find the problem. Most independent mechanics will not touch the Spark CVT's., so CVT issue..dealer. Link to post Share on other sites
