Low idle speed

[Blimp 8801]

Hi out there in forum land I just fitted a cruise control to my 2007/8 Alphard works a treat but for some reason the idle speed has dropped to just 200rpm the engine shudders and sometimes stalls have i fitted the cruise control incorrectly or does this happen if it does how do I get the idle speed back up again 

cheers

Hi would disconnect the cruise control and see if it goes back to normal

Maybe a dodgy Idle Speed Control Valve or wiring. Try disconnecting it and see if the problem remains first off.
