Best Answer

I had to try one additional part. I thought the pressure regulator resolved my problem. With an outside temperature at 45 degrees the car started up great. An outside temperature at 65 degrees caused the car to stall after the initial start-up. The intake air temperature sensor ($16.00) was replaced and this solved my problem.
