sounds like the hose has come loose from between the turbo & manifold. That'd be my guess.

Has it gone into limp mode.It could be 1 of many things.You will need to drop into a mechanic and see what code comes up so you know which sensor is rooted

 

[Old.Tony]

+1 on getting the codes.

If your MAF (Mass Air Flow) sensor in your intake has gone south (it does happen) your ECU won't know how much air it's getting, so it's not going to let you play nice. Limp mode restricts the engine so that it can't damage itself - usually that's a good thing.

And until you know what code is being given by the ECU, everything here is guesswork at best because textual diagnoses just don't always work.

It could be an oil feed/pressure issue, radiator temp sensor, O2 sensor in the exhaust - who knows, until that code is revealed.

thanks, yeh it is limp mode ,just thought id let ya's know that ecu light comes on first then boost drops to ab out 8psi and its just gutless . will take to some to get tested and post up what senor it was thats fucked,,

Do you have a power chip in it?

 

[SimonD40]

Sounds like a turbo over boost, have you blanked the EGR and not changed the vacc. lines around?

Shane are you still stuck ?

I have a working MAP sensor you could try.

Let you know if you wanna try it.

My spare only cost me $30 second hand from a wrecker. Was on mine for 6 months until I got off my arse and put the brand new one I had on. The original I snapped the barb off.

 

[Dave]

Oh and Tony.

Only GU Patrol spec ZD30's run the MAF.

D22's run a MAP sensor.

Are you still trying to flog that sensor....

.

 

[Dave]

Na I plan on keeping it.

He can try it, to see if his is stuffed.

I want it back so I have as little as possible down time.

 

[KraftyPg]

You should never have downtime you own one of those Super D22's

 

[Dave]

I broke the original one.

Go the 22's.

mine did that just after putting in a new turbo. just had an inspection and realised turbo hose had cracked. hopefully when I replace all is good.
