2.2 not playing
« on: 04 March 2008, 12:37:42 »
Hi all,
now the motor is taking the rise.  It will start, run for approx 5 secs at idle and then cut out.  There are no codes stored. Over the last 2 weeks it has had crank and cam sensors changed which cured the rough running. It had a MAF changed yesterday because they were the only codes logged. It has had a new fuel filter and air filter changed today (fuel filter looked like the original, car has 53K). I am now at a loss, any ideas would be most welcome. :(

I had to use jubilee clips to secure the fuel filter after the fragile bits broke, it is fully secure with no leaks.  Just had a thought and ran it with the MAF disconnected, idles well and runs sufficiently to drive ok but obviously not totally happy. Reconnected MAF, symptoms as before, any ideas?

I was wondering if the filter could have been sucking in air

Given that  I can drive it with the MAF disconnected (obviously in limp mode), I've discounted that.  It's bizarre to say the least.  Checked again for codes, zilch. It's getting on my melons now!

Air leak?

EGR valve stick open?

Its this sort of fault that the live data needs checking on, even a Vac test would give some clues.

Trouble is that willy nilly part changes only add to the unknowns....

The bizarre thing is that it will run relatively OK with the MAF disconnected.

Where abouts are you?

I assume the MAF is fitted the right way round?

I'm up in the north of scotland. MAF is fitted correctly. It idles for 5 secs or so whether it's hot or cold and equally, drives ok-ish with the MAF disconnected whether hot or cold. I shall give the throttle body a thorough clean tomorrow and see what happens.

I presume the cam sensor is a genuine Vx one?

By the way, it's best to keep updating your original thread, instead of starting a new one, it lets people see the history :y

Cam sensor is vx, MAF is unipart. Throttle body cleaned and sparkling, symptom persists, drives ok with MAF disconnected, no codes logged with MAF connected, garages around here booked up for nearly 2 weeks for diag'.  Point noted about threads, cheers.

MAF  faulty, lucky enough to have a mate with the same model, tried his MAF and whoohoo it works, back to partco and try to explain to the mentally bereft geezer that it was unserviceable on fit, met with shrug of shoulders and ' it could be some other fault mate' etc but on explaining mates known serv' unit and then successfully fitting replacement in the car park, he became all apologetic. Never mind, 2 weeks of grief and now a happy Omega driver after a serious thrash on country lanes this afternoon. Thanks to all for the help, this is an ace forum, hats off to you all!  :) :) :) :) :) :) :) :) :)

Good news and it also highlights the two things I always preach...

1) Never change anything until you know what the cause is as changing random parts adds more unknowns

2) Just because its new, doesn't guarantee it will work!
