Re: Renault Clio 2003 - Engines - Loss of power and Warning Light
Depending on what fault light is coming on it seems as though replacing your coils will solve the issue
Did that back in post #171 and unfortunately it didn't make any difference.
My problem seems to be a fuelling issue...
Oxygen sensor #1 has a very 'lazy' waveform although the switching voltages are logical
Oxygen sensor #2 is reading around 0.8v - very rich
Long term fuel trim is -14.8% - not extreme, but it's trying to lean the mixture and seemingly not having any effect.
If the car isn't sold 'as is' before, next I'll check for leaking injectors and replace sensor #1.
