this is doing my head in now!! car starts, cold start valve must be working fine. when the car has been driven for 10 mins or so the idle goes very low and up and down abit and if you dont rev it it stalls. now iv cleaning the aav and had a different afm on it and still does it, i think the aaf is dodgy.
will a r32 gtst one fit on a r32 gts n/a?

any ideas?

cheers.

Sounds like a vacuum leak, split pipe.

When pipe gets warm/hot the split opens.

Listen for sucking sound under bonnet when hot.

i have looked for leaks but cant see anything really there is a sucking noise but its coming from the air filter.
think i might try a different idle control valve , does anyone know if the gtst one is the same as the gts n/a?
