certainly a possibilty I suppose would help if I could locate the TPS  ;D

another suggestion was the accelarator Potentiometer cant find that either  ;D

At the back of the engine there appears to be a small pot operating on a vacuum that mirrors one on the front there is a small  metal rod that goes in when you use the accelarator but then appears to stick before coming back out.

Interesting enough the rev counter is acting in the same way when driving or ticking over it sticks as you accelarate sometimes it sticks then brings the tick over down from its high reving

Sorry I only have laymans terms for you ;D

This is so frustrating I mean how can a Vauxhall dealership not know iys driving me mad.

The live reading were posted by Entwood way back when in November 2011 when we first talked about the engine managment light coming on.

At the time the MAF was suggested but I tested this recently by unplugging it as advised the first time i did it there was no change engine ran from cold to 80 as normal then straight up to 2000revs.
The second time I did it it went up to 3000revs after reachong 80 my understanding was that if the car ran better with the MAF unplugged than this was the problem if it didnt then the problem was somewhere else.

So there we are not any further forward and no more money to spend :'(

Just had a possible break through but need your thoughts guys

Could this be linked to the throttle position sensor / potentiometer ?

I know its connected to the throttle body somewhere but cant find it for looking

Wish I could guys but stuck at work no such thing as bank holidays for me  :'(

I suppose if im honest what got to me is that a local garage that my mate has used for many years not cheap but reasonable said they thought it was the throttle sensors 2 hour job £50 an hour plus parts but no guarantee that it was the problem until they took it apart  :( they suggested go to the dealership for a more accurate diagnostic and it hasnt helped at all >:(

I asked the dealership about the throttle sensors they said the throttle body had to be changed before they could progress further, I dont really think they wanted the job.

I have started to give up hope  :-\

latest update for all those following :-

So I took it too the local Vauxhall dealership £70 for a diagnostic the idea being that their system being specifically for Vauxhall and not generic.

Their findings were that they traced it to the throttle body and it needed to be replaced at a cost of £650 not just that it might not be the full problem but they couldnt go any further until it was replaced what a waste of time and money.

I told them that I had already replaced it twice but they said not with a new one and the old part I had purchased might be faulty although they had taken it apart and cleaned it at no extra cost and could find nothing wrong.  ???

My local garage had suggested the throttle sensors but Vauxhall didnt think so but kept saying the 2.6 v6 had often caused them problems. :o

I have noticed different numbers on the various throttle bodies I have used 8, 10, 12 so maybe it has to be in sync with the car but can find nothing to support that.

I still have the original so maybe put it back on but replace the faulty readers who knows  :(

Booked in to another garage on Monday hopefully they will be able to help seems im seeing faults where ever i look now so i might as well post pics of the whole engine  ;D

Has been another suggestion that it could be linked to the cruise control despite the fact that i have never used it ? might be worth having a go at disconnecting it if i can work it out

Short of that its the local dealership  :( probably charge more than the cars worth :-\

wouldnt be amazing if it turned out to be the lambarda sensors after all this

OK guys did as instructed disconnected the MAF and ran engine.

You guessed it fault still there  :'( engine reving as usual to 2000 revs without coming down unless I persuade it.

Went back to garage but no real help other than to say all leaks etc checked for.

Think I may have to try the throttle body again this time with a complete exchange just bought a Bosch one on ebay hopefully will do the trick

OK great i will give it a go somebody was kind enough to give me a link to the MAF position in the engine as a picture but is from the old site so not sure if its the 2.6 or not really worried about pulling out the wrong connector

cant do anything until tonight stuck at work  :(

So my understanding is if it runs better with MAF unplugged thats what is faulty is that right ?

when i fooled with the throttle control body and it ran better theres no connection you think ?

ok i see MAF mentioned alot soi will have to see if i can identify it being an idiot im only going to unplug the wrong bit.

The spindles is an interesting thought when i dismantled the throttle housing in idiot mode I noticed the spindle passed over tiny flaps which all seemed crincled on the one in the car and not on the replacement one of course by thet time i had ruined everything

well he took it off me for the day so i am presuming he did all necessary checks he reset the engine management light a few times but i told him that wasnt it which he agreed

he was 70% confident it was linked to the throttle body and like i said it did run a bit better when i moved parts obviously i made an error in judgement in not doing a proper job as apposed to moving bits from one to the other.

im a bit of a techniphobe can you tell me more about the MAF what it does etc and how this will help me
