The vehicle is a V6 Petrol SWB Shogun. I know these are thirtsty beasts but this is REALY thirsty. The exhaust also smells of unburnt petrol. On my Motorbike I can balance or syncranise my throttle bodies and "tune " the ECU in much the same way as you can change the air/fuel jet on a carb. This has helped clean up a smelly exhaust and improve fuel consumption. Is it possible to do the same thing on the V6? :beer:

OK so I ve found out that there is only one TB - no need to sync. But there must be some one out there who has had fuel consumption problems over and above the normal thirstyness of the 3.0 V6! :grouphug:

Often overfueling on modern injected engines is due to a mal-functioning O2 sensor. If the sensor does not work correctly the ECU puts into a closed loop mode and richens the mixture considerably. O2 sensors only last approx 80k and then start failing especially when cold. They need to get up to 600C for them to work which is why many modern sensors have heaters in them. Mitsi's do install two sensors (in front and behind the CAT) on later models but I am not sure about yours as its probably pre 96. So you would have to work out from the manual on how to check them without removal and then replace. On Other cars you just short two wires and measure the voltage from the sensor during various RPM's.

Thanks mate :beer: Ill take a looky
