	I cleaned the connections on the air flow meter last night and checked the wires were ok. Just used WD40. Also sprayed a bit around the idle speed control valve, couslnt see much so just randomly sprayed in that direction lol. Drove it this morning and it idled at 900rpm every time i pulled up. and seems smoother. wonder if it will stay same though!

	wow loads of replies. my eml comes on very occasionally. usually on a long run on motorway but is very random. is more jerky when it comes on though. i have a new ISCV so gonna fit that and see how it is. cleaned connections up on the airflow meter so will see how that is. gonna try the paperclip test i reckon. I am thinkin prob airflow meter or lambda sensor maybe.

marks_corsa	posted on 10th Sep 05 at 10:31
	Yea mine is also exactly the same. Revs higher on idle, EML comes on after about 2 mins of engine running and stays on, jerks at 3000 revs as you let off the accelerator!! I am NOT impressed!!
O.T.G	posted on 10th Sep 05 at 10:07
	i have same problem with car jerking at low revs. maybe they just cant handle being driven at low revs ;)
ash_corsa	posted on 9th Sep 05 at 22:44

	got a corsa Gsi a few weeks ago. It seems to idle a lot of the time around 1500rpm. sometimes lower, sometimes higher. Also the power feels a bit jerky, especially at lower revs. flat spots up the rev range. Have fitted new plugs, leads. changed oil. new cam belt kit. Gonna try an air flow meter on it I think next. Anyone else experienced similar problems?
