hi
i have a saff cossy 4x4 and when its up to normal temp and youve just pulled up at lights etc the engine starts hunting between approx 500-1000 rpm. what could be causing this is it the throttle position sensor or idle control valve if it is one of these were are they located.

also whats the best gap to run your spark plugs at the old ones i took out were set at 0.27" and hand book says 0.40"

old plugs are denso new plugs are champion

thanks
mark

 

soundz like the idle control valve, its on the throttle body

 

Lose the Champions use motorcraft, plug gap 0.7mm, mixture sounds weak.

Cheers
