And so it continues.... having fitted the throttle body, IACV, and ECU water temp sensor the darn thing still won't idle. From cold it insists on running at 1600rpm even when allowed to heat up till the fan comes on, the only way to get it to idle is to turn it off and re-start then and only then do I get a 1000/1100rpm tickover but if you then take the car out and redline it or progress higher up the rev range then 1600 rpm is the order of the day once more, turn it off and back on 1000/1100. If I adjust the idle down (by twiddling the butterfly stop on the t/b) when it insists on 1600 then an idle can be achieved but if the car is turned off and on again it sits there trying not to stall doing a self blipping of the throttle (which I assume is an anti-stall thing programmed into the ECU). Only two things remain to be replaced one is the manifold pressure sensor the other is the ECU itself, both have checked out fine on a Rover test rig previously. HELP !
