yeah see thats where my diagnostic skills draw a blank!

it's pretty basic on the clio with just a map senser, throttle position, iscv, temp senser, injector, crank senser.

tps, map, iat & injector is all on the injection unit itself so am going to replace that first and then map/ecu.

vacuum pipes are all good, wiring appears all intact and good, any further advise?
