Cheers guys lots of good advice here.  The car failed its MOT on one trackrod end and the battery not being held in place by the proper clamp - the latter a new one on me especially as the normal wiring holds the battery rock solid.   After the retest I asked the tester if he had noticed anything of concern at the back end and he said that the only thing he had noticed was that the front suspension felt rather 'soft'  but that was all.

I'm going to keep a close eye on that tyre wear and but the geometry experts in Chesham are a long way from here (we have just moved up to Cumbria) - anywhere in the North with a good reputation for steering/suspension?

Top of wheelarch to floor is 695mm on each side. The car appears to sit as I would expect with no sign of a sagging rear (!).  With new tyres the back end does feel better planted but looking at the condition of the ones that came off I'm not surprised.  I'll see what the outcome of the MOT is tomorrow then I'll check the rear suspension as suggested. The Omega certainly provides a long-term learning experience.

No, car has not been lowered and the springs are ok. Tyres were new about 10k miles ago and the problem was not apparent then .  The wear is so bad on these edges I thought the tyres must have been catching something on the car itself but they are not.  Strange that both sides have similar wear.  I'llget the old girls through the MOT and follow up with an allignment check.

Thanks for the ideas.

I  have just spent the morning checking the car (2.2i) prior to the MOT on Tuesday and having removed each wheel I came across a previously unnoticed problem.  Both rear tyres have worn very badly for about two inches on the inboard edge of the tyre.  The nearside tyre had worn so badly that there were two one inch long tears in the outer wall.  Other than this the tyres seemed to have worn ok. It's new tyres tomorrow but what are the guesses as to what caused this uneven wear?   I should point out that the tyres were not main brands but budget tyres I have used before with no similar uneven wear.

I had a similar frustration but it turns out not to be the bulb.  The bulb holder was the problem, in particular the metal strip at the bottom of the holder that makes contact with the bulb had become flattened rather than standing proud to act as a spring and ensure contact with the bulb.  Worth a look.  I just lifted the metal up slightly with a pair of long nosed pliars.

I can't check the switching but have just returned from another run with the new lambda sensor fitted and I have to say that the car is running better than before all the problems following the MOT :y :) :y.   No error codes - no yellow dash lights so feeling a little smug.  I'm just waiting for the engine to cool down a little then I'm off to change the oil: this will definitely be an antidote to any smugness as it's already touching on freezing here!

I'm off to Cumbria tomorrow for a couple of weeks and, if you're up to it, we could have a look at that lambda switching.

Fitted the new MAF sensor and engine starts well . :y..this is with the original lambda sensor in place, not the new one.  Seemed a little hesitant a few times and the gear box seemed less smooth than usual but after a good run everything seem perfectly normal in terms of how it runs.  The only downside is that the yellow light was back on and the same fuel trim error message (P0170) was there, as were two other error messages P0100 Air Mass Flow circuit error and one the number I forget but was the engine torque error.   Cleared the codes and had another run and the error codes have not returned.

After the engine has cooled a little I'll change the lambda sensor to the new one and see how it goes.  So it looks like the AMF sensor was the problem though I remain suspicious that the old lambda sensor may after all be duff.

This has been an interesting experience and I have learned lots.  I chose the title of the thread because having had all the weird errors generated by a bad cam sensor in the past I had decided that there is a great risk of being misled or confused by the codes and so it turned out to be.  Thanks to Entwood and the other inputs we seem to have cracked it.   I'm keeping an eye on the error codes but now I won't be so readilly intimidated by them!

What a fantastic resource this site is 8).

My head hurts too ???   

Just a brief update: I cleaned the MAF sensor using an electronics cleaning spray (shouldn't affect any electronic components) and took the car for a run.  I thought the problem was solved as initially it seemed to run just as I would expect but once it started to warm up the hesitation was back but nothing like as bad as it had been although I'm finding it hard to be objective about this. I should point out that I did reconnect the MAF sensor for this test. Does this support the idea that it is the MAF sensor causing the problem?  A new sensor is on the way and will hopefully arrive before the weekend is out.

Thanks again to Nige for taking so much time helping sort this one out.  I'm not sure if it helps 'Confused of N. Wilts' but I wonder if this has been a simple problem of a duff sensor sending data that puts the ecu out of range and therefore making any other inputs meaningless??  This would explain the fact that the lambdas are not switching as the ecu has now 'locked' into an extreme solution.  This is probably what has been discussed (?) but I need to make sense of it in my relatively simple terms.

Once the MAF sensor has been fitted I'll post an update.  Once again....thanks for all the inputs.

Yep- drove home with the MAF disconnected and it was almost a relief as it was certainly much smoother even if the power was clearly down.

I think I'll get my hands on a MAF sensor and see what that does....if it doesn't change anything then I have reached step 2 of being an Omega owner.............building a collection of working sensors to compare with the ones on the car ;D

It's been an interesting experience so far and it has improved my understanding of the systems no end.  Any thoughts following on from Nige's data are welcomed and many thanks to those responding.

Changed the lambda sensor back to the old one and straight away it came back with the P0170 error code.  I think I must becoming super sensitive to the sounds of the engine but tickover still seems a little rough.   Anyway back to Nige's now to put it on his meter and see what gives.

Wow- such fast responses.   Thanks to all.   Going in reverse order The lambda sensor changed was the front one and it certainly got rid of the error code. Whether it was the correct one I can't answer.  I did try running the car with the MAF sensor disconnected with no better results and probably slightly worse.   The coil pack did have oil coating the plug connectors and these have been cleaned thoroughly.  I am aware that they can fail after an oil 'bath' - the low power and unsteady running could indicate an ignition problem  but i don't hear any hint of misfiring.  Oh to have a spare car to swap parts with. 

Entwood, I can attempt a trip to Royal Wootton Bassett - is anytime in particular good for you?  In the meantime I'm going over the engine with fresh pair of eyes to be doubly sure I have not done something stupid in my cleaning!

Sorry I can't read the trims on my reader and there are no stored codes......the P0107  was the only code that has come up (other than the recent low torque message which I assume was due to the power issue giving the gearbox a problem) and that vanished with the new lamda sensor.

Hi everyone,

I'm new to the group but have been exploring the site in some detail as an owner of a 52 plate 2.2cd auto.  The car has recently covered 100,000 miles and a few weeks ago James (The Omegamechanic :y) fitted a new cambelt and gear selector switch for me.  What a find James is, and such a knowledgeable chap!

Last week the car failed its MOT on the emissions and the garage identified the problem as the lambda sensor (the error code P0107 kept appearing).  I changed the sensor and the error code went away but the car has not been running well.  On a long run it was clear that acceleration was fine but there was a noticeable hesitancy when cruising at a steady speed.  James pointed out that the cam cover was leaking (oil in the plug wells) so I decided to change the gasket and clean all the breather pipes.  I did this and aqalso removed and cleaned the throttle valve assembly, replacing it with a new gasket.   After this the car started very well indeed but had a hint of rough running when idling.  A short drive was not reassuring as the car accelerated well but is even more hesitant than before and struggling to run at a steady speed.  A check of the error codes showed only one that related to not enough torque from the engine.    After another check to ensure I had not missed any poor connections or loose pipes I started the engine again and despite an easy start it seems to be running rougher than ever.  Going through all the posts of similar issues on here isn't helping me with this problem.  I have checked and double checked the electrical connections, and made sure all the pipes are connected properly but the problem seems to be getting worse.     

My thoughts are that the fact it is starting well suggests that the ignition system is probably ok, and based on anexperience with a previous car (30 years ago!) the symptoms could suggest fuel starvation.  Could it be linked to the MOT emissions failure - could it be the mass air flow meter?

I am so aware of how easy it is to chase my own tail when tracking down the cause of such problems so any ideas would be of help.
