Arrow Does scraping your y-pipe set off knock sensor??

Just what the title says. My y-pipe scrapes when I back out of my garage. When the engine is cold it wants to die after I scrape??

This happen to anyone else??

A Y-pipe scraping the ground will not cause KR, but a Y-pipe hitting the bottom of the floorboard will. The stalling could be because the engine isn't warmed to operating temperature. However, you need to isolate the problem and see if you can cause it to happen under different conditions.
