then I suggest the bloke does this to get the code

Its the paperclip method everyone always goes on about on here......

Bridge pin a and b on the diagnostic port and count the flashes on the dash. Look on topbuzz for a guide.

if it was free why have you not explained how

The halfords thing flashes an led which you have to count, it also costs about £15. For free you can make the ecu warning light on the dash flash and then count them to achieve the same thing!

yes then it tells you waht the light is on for. the GM fault reader does the same thing excet is a bit more hi-tec :lol:

The halfords things are useless, just flash out the codes on the dash.

if your lECU light is coing on. buy one of the test kits from halfords and see what the fault code is. they work well and are cheaper than taking it to a dealer

The ICV is located on the side of the throttle body, its a pain to get to with the standard inlet manifold. It has 2 torx head bolts holding it on.

Mine is exactly the same mate but mine only seems to idle in the lower regions never above 800 but all over the place under that amount realy doing my head in, I heard cleaning the idle control valve works wonders but I dont know where it is located mines a C16XE aswell, Regards Paul...

yet its annoying me now :( I dunno whether to try fitting some replacement parts on it or not, my mate has the same engine spare and if I can try bits n then see if it solves anything- car does not have egr as its an earlier engine thanks bud- how do I gain access to idle control valve then?

sounds exactly like problem i had on mine, apart from the ECU light coming on. It was the idle control valve on mine, had it cleaned and it works fine now!

could be idle valve ive heard the egr can cause probs and if the is a hole on the inlet somewhere

also u shure its not the cov that did it?sommit u missed

congrats on doin that btw

anyone?

my car idles all over the place, ECU lite in on and off like a popstars relationship, sometimes it ticks over at bout 1800rpm other times its at bout 400, and if I coast the car usually cuts itself out, is this a typical idle control valve problem? where is it located on my c16xe?
