hi i'm bill
welcome to just answer
please remember I am NOT there in front of you! my answers are based on your information
you did not specify t he engine in the wrangler but you are on the correct path, 99.9 percent of the time when a customer cannot complete get the vehicle to run a complete drive cycle AND they are following the correct procedures, (fuel between 1/4 and 3/4 a mix of highway and city driving and several overnight and warm starts) the engine computer software needs to be updated, and after the vehicle will complete the necessary tests fairly fast.
