I have had this happen to me probably 7 or 8 times. When I stop at a stop light and then take back off, the throttle will completely cut out for about 1 second then kick back in like my foot slipped off of the thottle. It happens around 10 or 15 mph and has happened at several different throttle positions ranging from a quarter throttle to WOT. I don't remember it happening until after I took the HC trap out and put the JET performance chip in and started running 93 octane. Last night I took the JET chip out but I still have a tank of 93 gas and it happened twice on one takeoff today (a slow takeoff). I was wondering if any of you smarter than me would know if the HC trap being taken out or running 93 octane on a car tuned for 87 could cause this? I'm going to leave the chip out and run 87 for a while and see if the problem reoccurs. Also, has anyone else had this problem. I searched but couldn't find anything just like this. I have 9000 miles on my GT. Thanks, Dustin
