hi there just had the head gasket done and all it sweet as there. but for some reason the fuel is crap. got 80 miles on 20 quid. i know VR6 are thrust but that takes the piss. and the car some times feel in a word lumpy. put your foot down and a couple couple of secnds late it goes. any ideas.

cheers every one

80 Miles for £20, that in my opinion is good, I get around 120 miles on a full tank, but I mainly drive it approx 7 miles a day in traffic

Temp senser causing it to over fuel?? It will more lightly be the one that talks to your ECU not the one that works the gauge. If you disconect each it should tell you which is which, Can't remeber which colour it is.

Apart for that fuel leaks?

Do you drive it hard? What you said works out to about 20mpg. Mine driven hard did as low as 13mpg, 17mpg mid way and 30ish on the motorway driven well, thats going off the car computer which isn't very reliable tho.

So that would mean mine is seriously losing fuel???

which sensores need to be replaced?

There are two sensers inside the black plactic thermatate housing, Unless you got aircon, Then theres 3. If you get it hot then disconnect them one at a time i imagine if you look at the temp gaugue it will show you which one is which. You want to change the one to the ECU, Not the one to your gauage, Sorry can't remember which colours which!!!, Does sound like your overfueling btw, works out to 15mpg. Alot of black sut in the exhaust is another sing
