Morning all - just joined as I'm trying to get my Omega running again after 6 months or so of it just sitting there, looking like a nice ornament outside the house...
Its running really rough, I'm assuming its the Idle Control Valve as once you rev it past about 1500rpm it settles down - I'm happy with the process of cleaning the ICV, but my question is, where is the damn thing and what does it look like??!!??
Cheers in advance!

its to the right of plenum (passenger side) connected with a gasket and a hose coming from the front (throttle) very close to ECU ..
and dont forget to check for air leaks.. :y

Do a paperclip test to check for fault codes? :y
-
Thanks All
I need to do the Paperclip Test - got to locate the relevant codes and instructions again though - remember it being online somewhere a while back...
Might have to change the habit of a lifetime and Google it!

See Common Issues and FAQ section for paperclip test instructions and codes ;)

Got the old beastie running again - had a spare ICV in the garage (didn't even realise it was there...) so cleaned that an fitted it today, along with the "spare" EGR Valve I had in there too....
Starts fine, ticks over fine at about 600rpm, but has no power when you accelerate and seems to "chugg" and struggle to pull...
Any ideas?
I still need to do the paperclip test - would you believe I can't find a flipping paperclip or suitable piece of wire anywhere!

Got a safty pin? cut the end off that works a treat.

Evening again...
I've finally managed to get a moment to read off the fault codes and now, to be honest, I'm more confused than I was before!
I got the 1-2 code as expected, then got a 5-7 and a 1-3-2 so that means - which is somewhat annoying as I've changed both the ICV and EGR for spares I had in the garage (although they could be duff too)
57 Idle Air Control Voltage Low
132 Exhaust Gas Recirculation (EGR) Valve Feedback Incorrect Signal
I also got a 9-1-2 sequence which to be honest has confused me somewhat - it was the first code that came out after the 1-2 sequence... Any Ideas?
-
I've now replaced the Idle Control Valve (again) for a new one but it doesn't seem to have made much of a difference if any.
Its still running poorly, but I've noticed that when its warm, its emitting a "rotten eggs" kind of smell and the exhaust is popping...
Any ideas anyone?
-
sounds like a prob i had. was the egr. took it off & used a old coke can to blank it off. runs fine now. worth a thought. ;)
-
ICV code will come up if a) the connector is not plugged in properly etc or b) you have an air leak (usually breather system) so look for vac pipes that have split/fallen off etc :y
-
Had the EGR blocked off before - might have to locate the blanking plate again - I took it off when I replaced the valve the other week....
Any idea what the rotten egg smell is?
