Mine seems to want to tick over at 500rpm, but it never stays running, which makes town driving a real pain in the arse.

On my 86 XR3i I used to have the idle was 750-900, is 500 right for the RS Turbo or do I need to up it.

If so... Then can I up it on the throttle body or cable or does it need to be done electriconically????

I need to get the rolling road'ed soon, is this something that the tuner will have to do???

Cheers
