Well that's an easy one.

 

The VSV (Vaccum Switching Valve) is the only thing inbetween that vaccum pipe attached to the fuel pressure regulator and the inlet manifold.

 

i.e. FPR->VSV->Inlet Manifold

Right, got to the bottom of it.....I think!

 

Had it analysed by Clive Atthowe in Norwich and the O2 Sensor isn't changing it's output (about 0.3V) no matter what you do with the throttle or put down its throat.

 

Trouble is that our friendly local Toyota dealer says the uk and J-spec O2 sensors are different.  Anyone know for sure?  Mine has 3 wires coming out of it which go all the way to a plastic connector at the front of the engine.

 

The other thing the Toyota Dealership said was that it would take about ten days to get one from Belgium!!(£121 + VAT)

 

Any ideas, Anyone?

Yep Jap Spec and UK Spec oxygen sensors are different part numbers.

 

UK  Spec 89465-19605

Jap Spec 89466-20020

 

Parts from Belgium don't usually take 10 days more like 3-5days.
