Citroen C2 not running correctly

[Liamv123]

Hi there ive got a issue with my Citroen C2 1.1, it's a 2005, what happens is when I am driving and press the clutch the revs will go up to about 2000 rpm then drop down to normal, it's doing this quite often more so at slow speeds, ive had it on the texa computer at work and there's no faults. I've cleaned the throttle body buy with it being electric there's nothing much I can do. Just wondering if there's any common issues cheers

Worth looking at voltages in the charging system & battery etc, these throttles can be sensitive, get a decent battery test, & look for a constant 14.2 v at he battery whilst running .
