Hi, i have noticed lately with the cold weather here now first start from cold ie. sitting overnight or all day at work, it barely cranks over as if its timing has been advanced a ton it wont do it for the rest of the day.I have done all the usual checks (h/gasket etc) .I have an ECU kill switch and if i crank it with the ECU off it winds over like normal? Any one else have a simular problem?

Ok,iguess no-one else has had a problem like this will try a new crank angle sensor

.Moving onto another thing does anyone know if you can make a EF ford idle control motor work as i have a throttle body off an EF ,would be a nice feature if it could

Thanks Ratta

not sure on the idle control motor

i'm having cold cranking issues too but its been since replacing the head, injectors etc. its a bit intermittent at the moment so trying to work out whats going on with the old rb30. i'm going to see if I can determine the injection pulsewidth when cold cranking to see if that is okay

Thanks for the reply Matt ,yeah its a bit weird the cold start thing like i said it might be the CAS, seen it before with other cars but usually only when hot .Any ideas on the ford idle motor control ?

Thanks Rata

mine kinda splutters for the first 15 seconds when holding the revs. didnt used to do it when i first got the car... so i've done something to it

wondering if there is a injector/water leak etc in the cylinders which gets 'cleaned' out once i hold the revs for a short amount of time

once its running there are no problems
