galbicake Posted August 20, 2019 Share Posted August 20, 2019 The car was dynotuned to stage 2 many years ago. I've noticed the past couple years the car will struggle with keeping steady idle between 700 to 1,000 RPM. It wrestles in idle and dips down to 300 RPM. It will go into Limp mode on really hot and humid days (mid 90s and above). MAF sensor and TGV deletes were replaced last year with OEM. Link to comment Share on other sites More sharing options...
