Sorting out the project trackshed this morning,got it started last week but tidying a few jobs this morning.fitted exhaust and went to run up to temp for the first timeno throttle cable fitted yet
Revs are mad high and have done the following to try and sort

Changed blue temp sender back of head
Disconnected iscv
Disconnected tps
Checked for inlet manifold leaks
No change , if I blip the throttle it drops to idle for a sec then revs up again to prob 2/3k

Unknown chip but for greens/3bar etc

Base idle screw in throttle body,is there a set position as in screw out fully then in five turns or all in and five out....

Cheers for any help...
