Hi,and hello.My punto 1.2 on a 99 plate when hot will not accelerate,i have changed coils leads plugs,injection unit,idle valve,and crank sensor,but still being a pain,but what it will do is if you un-plug the plug to the idle valve,it will run ok,i know i could leave it like that but i would like to sort it,anyone out there with any idea,s :bang:

What is fuel consumption like? Have you confirmed the lambda sensor is working correctly?
