How Many Oxygen Sensors On Mk1 V6?

[dipsomaniac]

have an intermittant problem where car is running lumpy at low revs.  have recently had a new middle section and silencer fitted and don't know if they disturbed sensors. have taken the car back and asked them to check and they said all was ok. have 3 fault codes:

 

00525 oxygen sensor g39 27-00 implausible signal

00561 mixture adaptation limit exceeded

00553 maf g70 31-10 open or short to ground intermittent

 

maf code might not be valid as i can't remember if i cleared codes since i temporarily disconnected the maf

have you tried to clean the maf with electrical cleaner????

[dipsomaniac]

no i haven't smudger. didn't think cleaning was an option as can replace for around £80 at gsf

Have a look at your coil pack,the sensors may be a red herring . If you disconnect the lamda and maf car will run on default settings
.

Please ensure you have also checked for airleaks around maf and clean the throttle body

cheers cyborg. i replaced the coil pack 7 years ago so may need to replace again.  car is driving ok at the moment but i have bought new vacuum hoses and intend to replace all when i replace the top coolant hose (ford are saying that they can't supply the top hose as it is now unsupported and vw are quoting 3 weeks) so all good fun.
