Could a blocked fuel filter or a lazy fuel pump be causing these issue's? I'm thinking if it could be making it run lean on tickover and that's why the Lambda is throwing up a fault.

If you can read fault codes surely you can look at the data list and see the output of the lambda sensor to the ecu?

Doing what it should be at idle and fast idle and showing rich on WOT and lean on over run?

Yeh that about rite. Basically 0 is rich 750 is lean ( or other way round) all an oxygen sensor does is constantly tell the ecu the fueling is rich weak rich weak so it keeps the air fuel ratio correct. The ecu ignores the oxygen sensor when you boot it as a richer mixture is required and also ignores when you are coasting or take your foot of while revs drop as the mixture is lean then. Sounds like it's working ok then. Strange one....

My black 6 used to keep putting up code 22 fuel air mixture adaptation which is down to lambda not being set up properly. You can do this on pug planet 2000 software. May be worth trying that. But as others have said swap ecu's with someone. If you have any mates with a 6 the sand phase you don't need an unlocked ecu just have to swap the immobiliser ecu and pickup ring as well then will work.

ok so ive just nipped up tesco....got in the car to come back, turned key to second click and while it was priming it started making a strange sorta gurgling noise. still started fine. do you think it could be related to whats going on? i havent noticed it before, but doesnt mean it wasnt there

normal? or potential sign of it about to die?

ive been on the phone to someone who has just come back from a holiday,he says knows these cars.

he said he had one in a little while ago and it turned out to be a failing crank position sensor. difference being if it fails completely it causes non starting issues, but if its just failing/weak/covered in crap it can cause what im experiencing.

ive taken mine off completely and cleaned it off, it had a really thick layer of crud on it so ive cleaned it off, its just started hammering it down so ive disconnected the battery to let the ecu reset while im having a brewski waiting for the rain to slow down a bit

how strong should the magnet be?

just need to work out how strong the magnet should be because if its gone il just replace it

in...ecu reset...no joy...back to square 1

its getting plugged in again tomorrow using a snap on bit of kit. its not low on fuel at all. was on the light when i got it but been on at least 1/4 tank since i got it.

ive used the car a fair bit today and the pump just did the usual priming noise so maybe just a one off

This is the case, if I remember correctly it was Buzzbrightyear who drove around for ages without realising his was unplugged and there was no difference to the way it drove.

as other thread so all info is in one place...

looks like ive got another fault/linked.

was accelerating on an A road earlier, and lost power. throttle was doing nothing. put the clutch in and started coasting, steering into the curb thinking it had died, stopped and the car was still idling. from there it drove fine using gentle throttle for the rest of the journey.

it did it again, clutch in, foot off the throttle, clutch out and back on and it drove fine again

any ideas? im thinking fuel pump

lambda and map have been replaced with new parts bud. thanks for your input though

yeah mines a phase 2. im sure the map sensor is working as it should because if i unplug it the engine cuts out.

if i leave it idling long enough it does seem like its trying to die.
