What an excellent read! I've printed that off and will be going through it tonight.

Many thanks,

no probs.. cant remember how i found it last night.. i'd seen it before though..

most of the stuff on that list has been done to my motor (inclcidng regular "italian tune-ups") apart from checking the PSV for a leak.. i might check the distributor sometime too..

I'm picking up some new leads, dizzy cap and rotor arm at lunch to, so hopefully (everything crossed) I'll be on the road to recovery!

I cant see how disconnecting the MAF would have much of an effect on the CAT to be honest.

You'll be running a much richer mixture as the ECU will default to a richer setting. Rich settings cause to much unburnt fuel to pass into the CAT which over a period of time will damage it.

^ Yup!

Right I have reconnected the MAF for the time being, back to sh*tty performance till I get a new one!!

[Overseer]

thing is.. you could find that it is inadvertently making the problem going away.. replacing it could do nothing as the cause could lie elsewhere..

You shouldn't be able to damage the cat, as a lambda sensor will be fitted. This will automatically lean out the mixture.
