It also backfires, spits and sputters when the revs go below 1k, during this process. Once it will run and hold the idle at runs fine. The car is tuned with SCT and has a X4 tuner. When I load the stock tune from the X4, it will not start. The starter does not engage, like the file is corrupted. Load the VMP tune in and it will start and run(with said cold start issues)
Sooo, I made a thread about this a week or so ago, looking for solutions and trying to avoid spending $300 on credits. Luckily, Decipha hooked me up with a stock cef for this pcm. I loaded it as a custom tune and once again, I get a no start condition. Has anyone seen this before and have any suggestions?
