Hi Scotty, My problem is 02 Mercury Mountaineer 4.6L it turns off when at a stop light for too long and sometimes it will do it just once or at every stop light and I have no trouble what so ever turning it right back on. So I have to keep revving it so it won't turn off on me. I got no service engine light or any codes popping up. I've been bumping heads with the so called mechanics we've got here in Laredo. Let me know your ideas. Thanks for the help...

try this cleaning and pray
