H I folks having issues with a Corsa D 60 Reg whilst changing up the gears the revs go up whilst pressing in the clutch , foot is completely off the throttle made sure of that , its just started in the last 3/4 days

Any ideas thought it could be the throttle body needing cleaned or the throttle position sensor

Usually dirty flap will cause car to cut out at lights as flap is restricted when closed.Might be inclined as an air hose leak could make car run faster.Diagnostics might have to be run if you cant see anything.

No engine management light on took throttle body off today cleaned it now its causing erratic idle mass airflow ok whilst driving nothing but jerking on lower gears after a while it runs ok

Check plug tops and coil springs for green colour as they regularly dont get a good connection.Older cars had a plug lead which slid over around the plug for a better connection.

Yeah head gasket seems ok no gunk on coolant cap etc normally that's a sign the idle was ok before I cleaned the throttle body but before doing that it was sluggish sometime difficult engaging gears also before the cleaning of the throttle body whilst changing gear it was going up in revs about 500 to 1000 revs whilst changing gear hence that's why I decided to give it a clean
strange thing is gear change seems smoother now but the idle is terrible

Yes think i heard the same ,did you get diagnostic done and no faults recorded as on a few cars had to run learn mode to get car to run normal again.
