Have you checked for a clogged fuel filter? How is your fuel pressure?
Check engine light on? If so, jump TE1 to E1 in the diagnostic terminal under the hood. Turn the ignition on and count the flashes of the check engine light. Write down the code(s) and post them in here.
Also inspect the air duct between the vane air flow meter and the throttle body. Make sure it isn't ripped or has any hoses rotted or disconnected that come off it.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
