Hi to all, have fitted rb25 engine into my s13, runs but idols very high, cold 3500rpm and when it warms up aroud 2500-3000 rpm?????

Any idea's?

First idea that spring to mind would be inlet manifold air leak

may sound abit simple but have you got the throttle cable attached to the tb and its too tight?

[S13_Dan]

nope throttle cable got play in, dont that before. Got front entry manifold so will ptfe all the tap'd hole that the person done before me.

Cheers

soz to be a dumb ass but if air was leakin into inletmanifold would it not die as afm would mong out as not readin correctly? or is that what could make it idol high?

Cheers
