Went to get the codes read today, the guy plugged the scanner in and went to start the truck and it turned over about ten times but never started. I got in and got it to start and it died as soon as I came off the gas. finally eased off the gas and it ran fine. No codes were present, light went off. I made it down the road about 4 miles and it came back on. Turned around and got the codes read. When im slowing to a stop the truck dies down to about about 200-400 rpm as im slowing, then comes back to normal rpm once i come to a complete stop. I checked vaccum lines and also checked the o2 wire for exposure. It has the 12" or 18" lead since the LT headers relocated the rear sensor.
