I'm new to this group. I have been having problems with my Vehicross stalling out when I try to start it on hot days, after driving for or awhile or in the evenings. There are also times when it rev up to 3,000 rpm after I do get it started. Does any on hav any ideas as to what the problem is here . I have had my vehicros at the dealer 4x and still they have not fixed the problem
