I have been having this problem for a while now. When I am accelerating at a low speed (no faster than 40 MPH) or coming to a stop, the engine wants to shut off. I was thinking fuel pump but I was told that when they go out, it happens all at once, not gradually. The only other option I can think of is the idle air motor. What do you guys think? Thanks in advance.

You may have a bad IAC ( idle air control) but try cleaning the

throttle body first. Remove the intake snorkel, have someone hold

the throttle wide open for you and scrub the back side of the

throttle plate and surrounding bore with an old tooth brush and

some carb cleaner. Be sure to spray some into the small holes

next to the throttle plate. That should help stabilize the idle. If

it still has a problem, replace the IAC.
