Loss of power!! Sign In

I’m currently driving a 2007 Vauxhall Corsa, which has recently started to lose power and causing it to stall. It will immediately turn back over and drive fine until I get to low revs, then will stall again. I originally thought it may of had some dirt in the tank, causing some sort of blockage, but not sure if this is the case now. Do you have any idea what the problem may be? Don’t want to spend much money on a repair, as it’s only my work vehicle. Any info would be appreciated.

We don't have this car here so I have no specifics but here is a generic fix for those symptoms.

First eliminate all vacuum or air leaks in the system (very important)

. 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.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
