Then it would run until it reach operating temp. Then stall and would not run until the temp dropped by 15°. It finally stopped running on my way home in a Blizzard. All this time I had No CEL codes. I thought it was the Ignition module because it was Heat related. The Pep Boys I use for Winter repairs, cause I only have a Shade Tree to work under!, Found it to be the MAS. They put the new MAS in, problem solved. But in searching for the problem they found that my CAT was bad. You could smell it but it did not turn Red Hot.

Also, I will remind you that New does not mean Good. I recently had a Complete rebuild on my Trans. With in a day after the repair, I found that the Torque converter, although brand new, was defective. It happens. Outside of cars, I use to build computers for Arcade games, when a customer would tell me that the game was New, I would tell them there is a reason for "The Lemon Law".
My point is, don't discount a part as the cause of your problem JUST because it was recently replace with New!
