Setting idle on 3.9 v-belt

Recommended Posts

I have installed the full kit from Nigel onto my 3.9 v-belt that was originally in a range rover classic. I got a pre-built ecu that was loaded with a map, I'm running ms1 extra 029v on megatune.

 As per the manual got the laptop to communicate with the ecu and got it running, only had the VR sensor to swap wires on which was good. 

After setting the tps and removing the pwm I started adjusting the hex head screw for the idle and cannot get it above 670 rpm, even had the screw out at one point and still can't get it any higher.

So can I get some pointers on where to go next ?

Is the bypass port all gunged up?

Thank's Bowie, hadn't even thought of that will clean that once I've got daylight.
