Oh dear, hope you kept the old cat. Pattern ones are very nasty!

Is P0170 your only code?

I believe the difference is just in cable length...

Thank you for the replie, yes P0170 only code, fitted new MFA and staight away found a different,engine appeared smother, fuel reading appeared better but 40 miles later guess what light on. Cat fitted by Local Exhaust dealer but they used earlyer garage part Lamber.Could do Cam sensor next but have just came in from garage and can herer strange noise from around exahust when started ,but stoped after 2/4 minutes or when engine warm could I have a Cracked manifold and if so would this cause fault.
Thank you

More likely the new pattern cat fitted is making those nasty sounds, can say enough how rubbish new cats are. At a guess you replaced it due to a failed flexi join?

Clean the throttle body first, clear the codes, then see what comes back 

[Steve B]

tunnie am i getting it wrong here the code he is giving is for a v engine...he has a 2.2

P0170 Fuel bank trim Bank 1

should be

P0170   Rich Exhaust 
P0170   Lean Exhaust

[tunnie]

Basically same thing, just says bank 1 as V6 has two banks and two exhaust. Where as 2.2 only has one exhaust.

[casared]

Had similar problem with my 2.2 four weeks ago turned out aftermarket lambda at fault.Fitted ngk lambda now like  new.For forty quid you,ve got a aftermarket lambda

[rockabilly]

Thank you all for your advise,the thing is I had a cat fitted went from home to Folkestone 180 miles no Prob,parked up for the weekend.Got in the car Monday morning left for home 4 mile on the clock light came on,do we call RAC no lets go 180 miles later, at 70 to 80 mph, we arrive home no Problems at all what is this all about,but if nothing else thank you for your help.

[ndmv6]

had this on mine...causes on mine were as follows
A . cracked and warped exhaust manifold.(common fault on the 2.2 petrol)
B. aftermarket lambda sensor fitted to front downpipe.
C. plug wells filled with oil due to gasket failure.
D. failed cat due to driving with eml light on whilst i was still trying to cure first fault(fuel trim bank 1 malfuction 0170)

THE CURE.
1 NEW CAT.
2.2 GENUINE LAMBDA SENSORS.
3.NEW GENUINE EXHAUST MANIFOLD AND GASKET + DOWNPIPE GASKET
4.NEW GENUINE MAF(DUE TO ONE FITTED BRINGING ENGINE COMPONENT LIGHT ON.
5.NEW GENUINE GM ROCKER COVER GASKETS
6 NEW BOSCH SUPER 4 SPARK PLUGS,DUE TO THE OIL COOKING THE PREVIOUS PLUGS.

Just seen you're in tetbury... I am in Gloucester with good diag kit!!

See my website - www.omegamechanic.co.uk for details of what I do, although with you being so close, and given the issues and costs you've had - I'll check it out FOC as a goodwill gesture

[JamesV6CDX]

First thing I Want to do is plug a laptop into this car and look at all the live data values...

[JamesV6CDX]

Also just for my curiosity, when was the cambelt kit last changed and do you know who/where set it up?

How does the car drive in itself?

Had a similar thing once before when a ham fisted spanner monkey got the valve timing totally wrong!!

[JamesV6CDX]

PS, (last post I promise!) please please do not let any 'garages' replace parts without a methodical diagnosis. If it's not misfiring, your coil pack is probably ok - etc.

Live sensor data is required. Can you take me for a drive while I sit in passenger seat with laptop?
