ok, next problem ive got.

from cold it starts straight up, only cranks over for a second but the idling is high and rough, it sounds like it misses a few times on tickover and splutters when i try to rev it.

when its been running a for while i'll turn it off, leave it for a few mins then try to start it up. it will fire then just crank without anything

ive disconnected the cold start, checked the auxillary air device, checked for vacuum leaks

when the ignitions on tho, the fuel pump clicks on now and again so could i have a leaking injector?
