Hi

I wonder if you could shed any light on this prob my mate having with his 4x4 cossie rally car.

When the car is cold it's fine and even at normal temps it's ok. When it gets really hot it looses all power and won't get up even the slightest hill. The engine will keep running and idles fine, it will rev ok with no load but with a little hesitation. Turn it off then on again and it's pretty much the same. Let it cool for 20 mins and it's ok again for a while. The ECU doesn't show any diagnostic codes. All the sensors have been changed one by one and it seemed to be ok after a new throttle pot but the problem returned after 100 miles.

Thanks

Mark.

 

Hi,

Look around fuel pressure regulator, or athmosphere fuel tank connection (i don't know english term)
