Has the cam sensor been changed? If so, where was replacement sourced? 

[Peterskinn]

Coil Pack and Cam Sensor both NEW - Cam Sensor Genuine Vauxhall

Have had it working intermittently and got to my garage with ECU Software - fault codes mainly pointing to throttle position sensor - and various other ones which would appear to be down to unplugging whilst the engine is running.....

Ran very well for a while then stop & start and the throttle pedal has no effect!  Am I unlucky enough to have suffered a throttle body fault as well??


Bring back Zenith Carbs and a cable!!

Didn't quite answer the question... where, exactly did you buy the cam sensor? In person or over interweb?

£57

That didn't answer the question either... I could buy fake cam sensors and punt them out as genuine for £57 and make a decent living out of it...

If the Cam sensor was purchased anywhere other than a VX dealer which required your actual physical presence, then I would suggest that the one fitted is a fake.

It came from the local VX dealer.

Yes it was £57 + the dreaded VAT

Runs beautifully - when it runs.

The reason for going on about the cam sensor is that they are around £80 approx

Did you personally go into VX and buy it then 

[Peterskinn]

Yup

I have wondered about starting a new thread - but here goes anyway.

I've had the car back now for couple of weeks during which time I've done about 600 miles. In an effort to cure the lumpy tickover I followed all the advice and did the throttle body strip/clean and whilst I was under the bonnet cleaned the oil breather, EGR valve and the MAF. Other than the breather pipe all was dirty but nothing appeared to be blocked

Started up and all worked OK even did a test drive and it certainly performed better.

Came to get in it today, started up  and NOTHING. It would start and hold a - sometimes erratic - tickover - but there absolutely NO response to throttle pedal input.

Checked the obvious things like the plug connectors etc - all seemed OK. Will have another go later - But (here we go again) anybody got any ideas?? 

If the code is P1555 then this is the throttle body (or pedal) but seeing as you have cleaned it;

Could be the butterfly sticking?
Did you take it out to clean?
Did you put it back the right way up/centered correctly?
Did you force it all the way open to clean?

All questions I asked/checked myself, see this thread, http://www.omegaowners.com/forum/index.php?topic=130904.msg1676240#msg1676240
note throttle adaptation not specific to migs but may help, throttle full on, ign on, hold for 30 secs, release and start

Good luck, I still have the prob and ignoring it for now

Hi - I appreciate the help and advice - esp the "throttle adaptation"

Other Questions:-

Could be the butterfly sticking? - seems stiff but i don't know how it should be - certainly it moves under a good poke with a screwdriver and I oiled the spindles in case I had been overenthusiastic with the carb cleaner stuff
Did you take it out to clean? Yes
Did you put it back the right way up/centered correctly? Yes
Did you force it all the way open to clean? Yes - I guess in my heart of hearts I'm wondering if I've been too heavy handed??

Stiff is the stepper motor being manually turned by you thats why I mentioned opening all the way

Same here, no throttle response. Mine seemed to be getting stuck and a few taps on the throttle body made it work, I had a spare which did resolve it  but not anything else still get P1555 but does not seem to affect the car so ignoring for now

[Peterskinn]

Blimey - where did that time all go??

As I write the car is going OK - now 1600 miles since gasket change and yes I got a new (Ebay new) throttle body.

Whisper it - but all seems well so far...

Heater is very poor - have flushed the system with a hose - which helped a little. I'm steeling myself for a poke and prod behind the facia - as seen elsewhere on OOF.

Other than that - new battery (old one gave up at the first cold snap) and a small coolant leak from the EGR valve to cyl head joint.

In the great scheme of things - I might leave well alone and wear a coat when driving!

2.2 heaters take a long time to get realy hot...around 5/7.miles of running in cold weather...i was a bit peed off with mine as i could not understand why it would not get hot,,,,,,asked the question on here about it and Tunnie said to bleed the system properly again from scratch which i did and although it still takes a long time to get hot..it is a lot better and does heat up hotter now..Tunnie has a 2.2 and he and others on here say the same thing..2.2 do appear to take a while to get hot
