My car stalls or dies when accelerating from a stop or slow speed.

It has done this ever since I had the battery replaced. The original battery died and had my mechanic replace it, ever since, once the car warms up it wants to stall or die when accelerating from either a stop or a slow speed. Sometimes it dies as I pull into the driveway or up to a gas pump or parking spot. It is much worse when the air conditioning is running.

The mechanic has "reprogrammed" it several times, no improvement. He also recently replaced a crankshaft sensor? again, no improvement or change. When it doesn't die, it suddenly kicks in with a jerk like there was a dead spot that I finally got past.

Have you checked things like fuel pump pressure?

The mechanic checked the fuel pump and it tested OK.

Can you tell me if you found out what the problem was? My car seems to have the same symptoms.
