Hi there madge1980 and a warm welcome to Renault Forums, I'm sure one of the tech guys will give advice soon, in the mean time if you do a search you may find something useful as I seem to remember a similar cry for help,

Welcome, do the revs drop at all? and if so after how long? I dont know what the issue is but the more info you can provide then the techies will be able to help.

 

[madge1980]

hi sorry no the revs dont drop they start going higher if anything. i recently replaced 12 valves cos the cam belt snapped. maybe ive put it back together incorrectly as i didn't strip it! Thanks again.

hi m8 it sounds like an air leak check the inlet manifold sounds as though it drawing air

 

[madge1980]

hi i will check but think the manifold is ok. could the problem be incorrect timing of one of the cams?

I have a similar problem with revving, my megane seems to idle at 2000 when I've just started up.

I can usually cure it by turning it off and back on (solution to EEEVERYTHING! ) but only if I've driven it with an idle of 2000 for a few minutes. Any ideas?

 

[madge1980]

thanks samross got it sorted now, the w**k**s who sold me the head gasket set gave me the wrong inlet manifold gasket, was sucking in too much air! selling it now though.
