Power surging when accelerating - 2005 Ford Futura

Sir, Have your Throttle Positioning Sensor replaced asap. Thank you for choosing FixYa.com

Check your air filter

Read fault codes . Check cat converter for failure /blocking exhaust system

Acceleration is defined as a change in speed, either a negative acceleration (slowing down) or a positive acceleration (speeding up). If you have constant speed, you are not accelerating.---------------------------------------------------------------------------------------

"SURGE" Loses power a little? Common problem is the EGR valve gets a confusing message.It sees many sensor inputs from the ECU and if one of many is sending the wrong message it will open up,falsely. FIND the EGR valve and plug the vacuum source and try the car again. if problem is not there,there should be an investigation by a trained mechanic/technician.


DONT leave it plugged.

Also ,have a transmission expert drive your car so he/she can feel the problem. A tranny shop" won\'t charge you for this test drive.

First check vacuum leaks. Some "check engine" light there? Try scanning the computer looking fault codes stored.

YOU HAVE FAULTY TPS SENSOR OR YOU HAVE WEAK FUEL PUMP OR CLOGGED FUEL FILTER.

Change fuel filter first, and go from there.

It can only be a few things for this. My neon had some power loss one time. I replaced all the wires, plugs, and bought a msd ignition coil pack.. try just checking your plugs and wires

Sounds like a possible vaccume hose leak?
