What MY?
Other things to try are Dump valve or Lambda.

where do you get spare MAF's from

 

MAFs just accumulated from friend going to Japan like

Defo not dump valve - and the lambda doesn't come in the equation until the car is hot - unless I'm grossly mistaken

 

Car is Legacy 93 single turbo. I've pretty much given up and sending it to a garage this Wednesday but would be good to have some idea what it could be. Thanks.

 

Narrowed down my dead car to overfuelling problem. Car starts but will die after initial combustion. If I keep my blipping the throttle car will stay running for longer. ECU not giving any codes - replaced the ecu just in case it was knackered anyway. Throttle sensor is giving correct readings. Fuel pump is working but could this be pumping too much?? Manual says it could be MAF (tried couple of spares but no different), air bypass valve (but have no idea where this is or what it looks like), fuel regulator (can't find this either!), water temp sensor and some other stuff. Definitely overfuelling cos removed plugs a couple of times during my investigation and all are fouled black (I've put some new plugs in the process). Can anyone provide any tips, general help? Obviously, can't drive car to anywhere for diagnosis.... sigh

What MY?

Isn't there an extra fuel injection into the manifold when its cold? could be that ...

and your are correct about the lambda it takes a while to warm up doh
