High Fuel consumption. Renault Laguna - noah
I have a Renault Laguna 2.0L 16v 98 volvo lump NQ7 or N7Q, I have had the exhaust replaced after the cat secton, as it was blowing a little.The fuel consumption has gone out the roof,this was the case before the replacement exhaust. its doing something like low 20's. which is alarming. Does anyone know if its likely to be a sensor of sorts, or anyone had the same problem.
