Was the stuck intake valve in the Recon in your profile pic or a JL?Mine didnt last 24hrs before it went from "pick up and go" to "push gas and nooooo"....engine light on and it was downhill from there complete with misfires. Service said it was stuck intake valve.... I thought that happens after emission problems on older vehicles.... not one with under 50 miles. Soooo I gave it back to jeep for fear of engine damage and future problems. Very happy in my 2nd jl.... drives like a dream! Just like people, most are good, but theres always a bad seed or two!
