For 2001 Ford Explorer Sport Trac. Nothing wrong with it. I live in South Dakota and when it gets really cold (0 degrees and below) it won't stay running until it warms up. I have to sit in it to keep it running. It sometimes trips the "Check Engine" (lean) light if I drive it before it warms up. Only happens on initial start up when below zero. I don't want to chip it so I decided to sell the kit. If I lived somewhere it stayed warm I would never sell it. Drastic improvement in throttle response. Also helped out in the power dept. and +2MPG.
