3b s2 coupe resurrection

I stuck the part number in Ebay, price plus post and packaging lowest first, was about £116 iirc, I will get the link tonight.

Where were the DS2500s from mate? I need some

Intake holds 30 psi only leaking through the engine.

Out for a drive, feels like a massive boost leak as soon as you get on the throttle mega rich. DV holds vacuum.

Trackday is booked for Saturday so need BOOOST again, or its life expectancy is getting shorter, and something with a NA v8 more appealing

[Error404]

Don't bother with an NA v8 you will be disappointed
Have you got any codes?

[newsh]

As above ^^

MAF died?

Lambda?

Was the PCV disconnected at the MAF hose when you pressure tested?

[andy10v]

No fault codes.

Intake was tested by removing PCV and blocking where it went into the MAF. Bung in the MAF hose and added air through a valve in the bung.

New lambda was fitted.

It drives perfectly off boost, idles, good on part throttle, and then massive miss/buffering on WOT, AFR is pegged at 10 on wot. AFR is 14.7-15.X on cruise.

My next thing was to parts bomb it with stuff I have in the garage

My old F5DP0R plugs (I fitted NGKs)
Newsh's; coil, leads, dizzy cap
spare MAF
spare TB-? any point really?

It has run perfectly with the parts currently fitted so I am looking for something silly/simple.

Worth swapping the DV?

[newsh]

I guess it could be plugs/leads, the missfire sending fuel into the exhaust and affecting the AFR?

Maybe FPR? Didn't you fit one recently though?

[andy10v]

I think PRJ said missfires show as lean as the lambda measures oxygen content, and when there is a missfire the oxygen is unburnt and then in the exhaust.

I fitted a used 7A FPR

[newsh]

I think I'd try the spare MAF first. Or wiggle the connector..

It does sound like you have murdered something

Thanks for the morale supprt

Newsh I will try the MAF tomorrow, and give the neighbours a rest tonight.

Sleep on it mate, I'm sure it is something simple

[K Simmonds]

Bummer! You seem to be encountering niggle after niggle, as Alex says sleep on it and try swapping out some parts like the MAF etc tomorrow.

At least you haven't got a clutch to change as well as a head gasket to do, got coolant going missing and way too much water in my catch can. It passes a sniff test and the compression is between 10.5 and 11 bar on all five cylinders so it's kinda gauling to have to pull it appart, there again I know she's in pretty good order rings etc wise.
