where is it on Efi inlet manifold ?

 

In the middle underneath the inlet manifold, it has a blue plug

 

There is none.

 

I thought glenis ment the cold start injector?

 

i have been told to replace cold start valve ?!?!

or whatever it is ?!

 

yeah if u had mfi system, but i dont think efi have one controlled by the ecu i reckon

 

what about the cold start injector then ?

underneath, blue plug as moonie said ?

 

no the blue one is on mfi like my car still mfi system, deffo think think yours is ecu controlled,

i would look else where for your miss fire, try the basics first and check wires.

 

it runs rough as fuk for about first 5 minutes...

replaced plugs the other day, leads are ok, as are cap and rotor arm...

 

fuel filter?, could be a sensor or something, sorry dont know much about efi,

 

Ahh read it properly now "EFI"

The EFI system has an idle speed control valve (controlled by the ecu) that varies the ammount of air entering the engine when the throttle is shut. If it running poor from cold it could be the coolant temp sensor goving the ecu the wrong reading therefore the ecu will be injecting the wrond ammount of fuel. The idle speed control valve could also cause your fault, its located on the left hand side of the manifold (looking from the front). Best bet would be to remove it and give it a clean out with some carb cleaner, see if the starting improves.

 

Moonie mate, where is it on this picture please ?!

 

EFI has no cold start valve.

ISCV ist the silver tube with a black hose running from it to the charge carrier.

Water temp sender is on the inlet manifold, at the back, underneath. It connects with a plug from the plastic casing, just like the injector plugs come out of.

Air Charge Temp is on the inlet, just visible on the right of your pic.

Check all vacuum hoses, MAP, plugs and leads too.
