hi guys

could anyone help me

my cossie is not idling right also popping sounded like the on of the injectors not working turns out there are fine but changing ifound that the fourth injector leed is not working, ie when you take the injector leeds of on 1 2 & 3 the idle drop and on fourth it does nothing?
also checked the power to the injectors and thats fine and re wired it

i have changed

coil
leads
spark plugs
distribution cap
rotar arm
injector

could it the 3 bar map senor or ecu?

IT could be ya ecu and also could be the wiring to the inj. Also check ya phase sensor but would of thought it do it on all inj if it was phase. If ya can get hold of the cossy tech manuel then it gives ways of testing inj s and wires but i cannot remember what it says. good luck

do a compression test to make sure its not a mechanical fault

Rolls

when mine did this I had a leaky inlet gasket... - worth checking with carb cleaner

Yeah i ,d go with rolls its worth a try.
But to improve your chances weaken the idle mixture first, so it just about idles .so if the easy start or carb cleaner gets into the inlet manifold it will be more noticeable.

It could well be a sticky injector, they do this if stood long enough as the fuel varnish clogs things up.
Try swapping the injector over to see if it moves the problem.
