guysat Posted June 24, 2013 Posted June 24, 2013 Hi everyone Im looking for a 2.2injection Idle control valve as its the last part to replace to resolve my engine issues. If anyone has one and willing to sell please reply I have put a 2.4 lump in with a carlton 2.2 injection system on. The car starts instantly from cold and ticks over fine @ 1000rpm until warm 3-4mins when the tick over start to rise slowly getting to 2500rpm. If you then switch the engine off and try to restart, she will not restart until left to go cold then starts instantly again...! I got to this stage 2-years ago.......and lost faith in her. But its time she was on the road and used, would really love to bring her to Billing but its looking unlikely again this year. Regards Guy
cam.in.head Posted June 25, 2013 Posted June 25, 2013 hi. what makes you think its the idle control valve? i would have thought that if it was faulty then you would have varying idle speeds all the time rather than a perfect start @ 1000 rpm.if you unplug the valve & control the air bleed by squeezing the pipe does it make the problem any different ?also is the idle bypass set correct. i beleive its done with a dwell meter to give about 35deg but i usually find that seems to equate to about 500 rpm when fully warm with idle air pipe squeezed fully shut.

In this warmer weather the car starts with the idle control unplugged and ticks over great 800rpm ish, a few revs and returns to a good solid tick over. With idle control valve plugged back in, it just does not keep a constant tick over. Would like to find a replacement or trial another one to prove it. Too late for Billing again this year Also when engine is hot, she will not re-start
mantasrme Posted July 8, 2013 Posted July 8, 2013 Don't have a 2.2 ICV but the Idle control valves can be tested and adjusted. The moving disc inside is connected to a metal coil of flat wire that is heated by passing electric current through it and slowly moves the disc around. Over the years this can go out of adjustment as the coil looses its spring. A small nut on the back secures a stud that is attached to the disc, loosen the nut and the discs starting position can be changed (you need both pipes off to see the air gap)
cam.in.head Posted July 8, 2013 Posted July 8, 2013 the 2.2 idle control valve is a totally different thing to the normal gte item. it is a constantly variable unit rather than a idle air cut off to lower speed as engine warms up.both types can & do go faulty.if you have a correct 2.2 set up with idle sppeed control box then having it unplugged & stable speed does suggest a faulty unit .(or a combination of malajusted air bleed screw & throttle flap adjustment.)throttle valve is adjusted by loosening to fully closed,turing stop screw in til it JUSTfrees off the flap then one quarter turn extra. air bleed adjust to give approx 500 rpm with pipe squeezed fully.
mantasrme Posted July 8, 2013 Posted July 8, 2013 Hmm didn't know that, although i haven't really palyed with a 2.2 But i have what is supposed to be a 2.2 injections setup sat on a 2.4 bottom end in the unit and that has a 2.0 style idle valve. Will have to investigate that a little more
cam.in.head Posted July 9, 2013 Posted July 9, 2013 the 2.2 valve is common to all the larger cih engines after about 84.(carlton /rekord 2.2,senator 2.5/3.0,monza 3.0)& judjing by the style of it many later vauxhalls too so should be easy to get hold of.it is a 2 stage stepper motor style rather than the early type which is just a basic valve to lower idle speed after a preset time(disc warms up & shuts off aux air) will have a look on ebay now
cam.in.head Posted July 9, 2013 Posted July 9, 2013 just had a look now. loads on but must say the hyundai & the peugeot/citroen type look correct. (how different can they be ?) typed in bosch idle control valve

Roy Posted November 22, 2013 Posted November 22, 2013 I have a 2.4 with 2.2 injection set up and had the same problem with idle control. A second hand one off ebay was also faulty so I had to bite the bullet and buy new. The part number was on the unit and it was the same as a SAAB one I believe. Ended up costing about £130 for genuine Bosch but cured the problem..

Shug Posted November 25, 2013 Posted November 25, 2013 What was the part number for the sensor? Worth a try on my dysfunctional one.
Roy Posted December 3, 2013 Posted December 3, 2013 (edited) I made the mistake of leaving the 2.4 temp sensor fitted and had terrible trouble with getting the car running. It used to flood massively until I replaced with a 2.2 sensor and all was well Glad u got it sorted Edited December 3, 2013 by Roy
