[QUOTE="mandkole, post: 1454415, member: 4630"] [b]chip issue??[/b] To update this, it just did it again on a cold start today. Muffled cackle and heavy smoke. It sounded just like the whisper file. After 3 starts doing the same thing, I flipped through all the chip settings and no change. I could start the truck on the no start position. Same whisper idle-- the switch did nothing. Removed the chip, reinstalled and restarted, it was back to normal. Could be a bad switch, failing chip, bad connection on pcm? [/QUOTE]
