Renault Laguna fuel injection fault

2051 Renault Laguna Problem

I keep geting a fault saying fuel injection fault on the system. This usually leads to instant lack of power and the car revs up and dpwn between 3000 to 4000rpm. Sometimes turning the car off resets the problem but mostly not. I have had a diagnostics guy out twice who resets the ECU. This makes the car settle down for 3 to 4 days then the problem re occurs.I have tried a new throttle sensor as this comes up on the ECU but it doesnt say its the fault code. He seems to think its a wiring fault between the ECU and throttle body. Please help

The same thing used to happen to me , but it always happenend when i was low on juice and like you have already said turning the car off and on used to resolve the issue until i was low on juice again , but since i replaced the turbo due to it blowing up i haven't had this fault since and that was about 40,000 miles ago .
