My Opel Corsa is losing power...

My 2008 Opel Corsa is losing power while driving. I had everything checked two weeks ago and have NCT this Thursday and I need help.

Hi Robert,

I'm afraid it's impossible to assess such a thing from afar. You say you had everything checked, but did you actually hook the car up to a diagnostic tool to see if the engine control unit has any error codes to report? That would be the first port of call. After that, it boils down to fuel, air and, if it's petrol, spark, so you need to check all the sub-systems.

It'll only fail the NCT if the problem is having an effect on the pollutants coming out of the exhaust, by the way.
