can anyone help me here. I have a problem with my idle.

When I start up the car, it gives a real lumpy idle. I cannot adjust the idle speed. I f i take out the idle screw, it will then idle around 2k , replace it and it is shite again. I thought the car would cut out when the screw was taken out

Also , when i disconnect the electromagnetic pressure actuator on the side of the metering head, the idle rises to around 1-1.5k. Plug it back on and it goes like a bag of shite.
at the moment I cannot check my CO level until I get it down for its MOT

once I can get this sorted it will be going to a RR for a set up.
Is my pressure actuator or metering head gubbed?

hope somebody can help.

 

Unlikely to be either TBH.
Its more likely to be a sensor of the black box itself.

 

may be able to source another black box. as for sensors, are there any resistance values that can be checked at all

 

HI,

Have you tried to adjust the co% to see if it runs any better,
as above maybe CTS or fuel pressure actuator or signals to it,
if the metering unit is not sticking, fuel pressure etc. what your email address
i can send you some info on cts etc, tried to post a picture of it but not very clear.
