Have you tried reply #7

[Boggy]

I'm glad you brought that up again, I've just got off the phone to Symes about that.

 As you know, the cam sensor has made no difference, I ran the engine and it was lumpy, goes straight into limp/ safe mode. I unplugged the MAF and the revs rise to a steady 1000rpm or so, it wont rev on the throttle (FBW). I plug the MAF back in and it still wont rev, I switch off and back on and it runs lumpy again but I can rev although it struggles. Also, With MAF plugged in, Light in shape of a car and spanner is on, Unplug MAF and that goes out and the EML comes on and vice versa!

Sorry, somehow managed to entirely miss this thread 

Has it had a decent reader on it, esp looking at gearbox? Symes - did you check the autobox fluid level?

Marston, thats basically Headington? I do occasionally get over to Oxford (Mrs TB's folks are in Horspath), but don't think I can this week 

[Boggy]

Gear box fluid is as it should be as per a thread somewhere on here, the reader I used was an OBDII, my mate couldnt get over to me last thursday as he had problems with his car. The car is in Barton at the moment, We are going to try and get it to Symes in a fortnight as I work stupid hours and I'm also working this weekend.

Anybody who wants to come and get a f^^^^^ headache sorted pm me an lets make Boggy a happy bunny-Half the stuff people suggested I've tried-AND no change so to Recap

MAF unplugged-no change
Gearbox oil-ok
new coil set
CAM sensor new
 
Cylinder head changed due to crack
Engine holds back=VERY unwilling to rev
Come on then=Whats the problem!!!

[TheBoy]

Willing to cast eye over, next time in Oxford, not sure when that will be. Absolutely no chance of being able to do anything physical - my own car is overdue an oil change   

[symes]

I can get the oil done - I'm sure the Useless Student will be passing back this way

Its normally evenings I get over to Oxford...

[Boggy]

I won't be able to do weekends due to obscure hours, As soon as the car is at Symes, I can leave it in his care and you can do as you please with her.

Just to give a broader picture, the head was replaced and running fine, EML was on as we disconnected most stuff with battery attached for the radio. Code reader at garage plugged in, codes all came back as not present, so cleared and ran fine. Following morning the EML light came on, I thought this was caused by the sheared bolt holding the EGR on. Took the car to Cornwall, ran fine from oxford until around the Avon bridge on the M5. Started to get poor acceleration and got worse further into the journey but still very drivable. Got me to Perranporth and got us around including trips to Lands end, St Austell and Bodmin. Then the problem got more noticeable around tiverton on the return home. Over the weeks it got worse. Recent troubles were, I had the rear unit with the EGR Removed to replace the EGR and bolt, obtained Vauxhall gaskets for this job, but had a water leak ever since. EGR Fine though, air leak like a vacuum which turned out to be injector seals. These were ordered from Vauxhall. this repair just seemed to amplify the problem. This has led to the car being stationary since.

Over to you guys

[TheBoy]

OK, so the problem is related to the head swap.

I'll get my thinking cap on.

[TheBoy]

Out of interest, why was the head replaced?

[Boggy]

Basically coz I'm a tit! 

 Well, I was that particular day. When I bough the car it had already had a cam belt done, but the car started to overheat weeks after buying the car. Until then, the car ran like a dream, I loved driving it. Anyway, I pulled into the garage soon after noticing the heat and message about coolant level. No water in the expansion tank and no sign of a leak or steam. I put some antifreeze and water mix into the expansion tank, I feel embarrassed as this is a schoolboy error, I heard a tink noise from the head, I dreaded the news that it was the head cracking, The mechanic who done the work said that the water pump looked very old and the bearings had gone, Had I known, could have sorted that ages ago. Anyway, new water pump and cam belt went in but the car started overheating soon after, using water etc, steam like you wouldnt believe! Car conked out, and thats why the head was changed

HIYA

I had a similar problems with my 2.2

First time it was a hose that had fallen off somewhere around the  front of the throttle housing. ( wouldnt even start )
Second time it was the same hose that had  cracked and it ran like a  Donkey.

[ingsy]

had similar problem for a while turned out to be a worn fuel pump in the tank not shifting enough fuel forward fast enough.
.   fited new pump no further trouble from this source
