Hi all
My 1985 Rangie still runs the 3.5 V8 and recently I have noticed a considerable rise in fuel consumption. I am lucky to get 350kms to 80 litres mostly around town at the moment.
A mechanic who was doing some other work on the car said it could be the fuel sensers that regulate the amount of fuel sprayed into the cylinders depending on the temperature of the engine. Apprarently there are 2 of these on the rover v8....somewhere
I am just wanting to know where these sensors are and are they easy to replace?
Cheers
Andrew

is yours a late 80s model with the flapper type air flow meter?
if so start by checking a few things:is the cold start injector staying open/energized?,is the coolant temp sensor working properly?,maybe the air flow meter is playing up?try with those things mentioned to start with.

One coolant sensor runs the gauge only. This has only one wire and is usually next to the thermostat housing. Forget that one at this stage.
The temp sensor you want is at the front of the inlet manifold usually facing up, and has an injection type plug on it.
Sometimes it is only a dirty connection, so pull off the plug and clean the little prongs with fine sandpaper , or maybe a nail board.
There is an injection diagnosis procedure in the manual, but quick and dirty the resistance should be about 400 Ohms at 88 C. The higher Ohms it is the more fuel the ECU tips in.
