my daily runabout orion 1.6 cvh efi is fine when cold but when it warms up it is lumpy as hell on light throttle, I have changed the map sensor, plugs, iscv with no joy
does the ecu get a signal from somewhere to say what the engine temp is (like a cossie) if so where is it cos I can't find it!!
if it's not that then what else can it be, it's doing my head in!!
cheers,
steve
