Thanks GBL, I would think the shops I’ve taken it to would have the scan tool. I’ve taken it to two shops now, and just dropped it off for the second time at the second shop. I can’t say I have any faith whatsoever in them now, when I picked it up last Friday, they were thinking EGR valve. I thought about that over the weekend, and, I don’t think my van has one single symptom of a bad EGR valve. When I dropped it off today, I questioned the guy behind the counter (not the guy who worked on it) why they thought it was the EGR valve, he said the testing done show it to be that, or the transmission. Transmission? An engine that sputters as you’re driving along is a transmission??? I know the TC has had tranny problems from the beginning, from what I’d heard, they were using a Ford Taurus unit back in 2010. Mine has the 8spd, but that’s irrelevant imo. How can they think it’s a transmission problem?
