When it first happened it died on me a couple of times and would not start until the next day. I did not check if it was fuel or spark related. I pulled the fuel pump fuse to clear the codes. Has not thrown another code since and starts right up. When I step on the gas it just seems to bog down and slowly picks up speed. Like its plling a heavy load. Will not rev up and ATX does not downshift. Basically like running on 1/2 power,
