Idle Air Control

Top sensor that screws onto the TB on the drivers side. Two hex screws hold it on and it has a plug into it.

Fuel pumps do fail slowly sometimes and not all at one time. Does it prime when you turn your key to the "on" position?

If it starts the pump is working at some level. I'd lean more toward a dirty fuel filter or injectors, but you never know.

Howl ong has it been since you changed the filter?

No SES codes? A failing Crank Shaft Position sensor can do that to the engine too. Get a scan for free at Advance Auto or PepBoys.

You think that caused all that stuff.
