vacuum leak.

 

If you haven't already blocked off the idle-up system on the throttle body then scroll through this to find out how:

If you have already blocked off the idle-up system then you should pull your inlet manifold off and check your gaskets.

I forgot to ask this on your thread but how come you removed your cold start thingo? Although by the looks of that it literally just lets more air in

Smallports just have an extra injector for cold starts.

^The idle-up/cold start thing is operated by the coolant temp and it was too much effort to run the coolant lines to the throttle body. The metal coolant lines need to be shortened when you put the 4A in RWD format, and when you shorten them you lose the pipes that take coolant to the throttle body. Doesn't matter, still starts on cold morning so it's all good.

Yeah, smallports have a way different system. Its not ever "cold" in Australia as far as cars are concerned.

Smallports have the same style wax-pellet cold-idle valve and Cold Start Injector setup as the bigports do (at least in FWD-land)

Spoken like a true Northern State Resident :P

In terms of needing the cold start injector. I doubt youd even need it in Tassie.
