hse 4.6 fuel consumption

had the car running on idle alot over the past couple of weeks while getting my problems sorted, i have not had a chance to really drive
it yet as i wanted to get them sorted.

i was hoping and expecting to get 12mpg around town and 20 on a run
but to my alarm the computer is stating 5 to 6 mpg. is this right, i know
the proof is in driving but i put 65 quid in last week, have done 15 miles
and idled for a couple or 3 hours at most and it is half gone.

is there a reliable additive to put in the fuel to clean the injectors or is
there a seroius fault????????

Hi i also have a 4.6 hse but iam getting just under 18 mpg around town, idont rely on the computer to much i checked it by filling up then seeing how many miles i got out of the tank. it sounds like you could have a problem. :mil80:

yet another problem???

am i ever going to get to drive this bloody thing?

any advice please, any common issues?

Hi buddy.

Don't panic!

Find a Landrover approved garage (not a main dealer preferrably otherwise it will cost you a fortune) and get them to plug in their testbook. This will show up any fuel/air mix issues.

Could be something simple like a duff sensor.

I used to get an average of 18.6 mpg with my P38.

Good luck!

thanks, think i will do that.

will it show up every fault with the car or just what they are testing for?

The mechanic can run a complete diagnostic check which will show up any faults with the vehicle. Some problems can even be cured by re-setting particular systems.

It's pretty cool!

right i will start making enquirys

where are you some body may be able to point you to a good indy

norwich, lots of rip off places.
theres one perticular place jsf, more expensive than main dealers.

for example i got a quote for £1100 to do blend motors
when hunters (dealer) quoted £700
peter scott also quoted £700

anyone mobile is best i think so you watch and learn

You could buy your own Rovacom Lite / Faultmate unit - save you loads in the long run given the hassles you seem to be having.

what work have you done on the engine has everyone will aggre 18 to 20 is the norm try first your air filter if you have not messed about with timeing or fuel when did it last have a service ie clean or change plugs these points all help fuel consumption best of luck Malrangee.

they are thousands arnt they.
i basically bought this car blind and inherited all its problems.
i have had jason round to sort loads out but am all out of funds.
just want to get this air con and petrol consumption sorted and
i think i will be happy, well reasonably

some one said distributer for fuel problems????????????

i would start with mas senser when you did drive it did it miss? was it slow to pick up? start it up go round and smell if you have rich petrol smell no distriburt on 4.6hse

18 to 20 mpg??? i'm lucky to get 14 -15 round town!!! and thats on the ever optimistic computer

i did get 122 miles to 22 quid of gas at 47.9 ppl, thats around 12 mpg on lpg so add 15% ish and 15 mpg isnt too far of the mark for petrol!!!

oh yes it definatly smells rich, whats the mas senser?

i get 15 ish round town when the bloody thing runs lol

maf sensor is on the air duct before the air box!

i went 4 miles round town and the computer said average 5.8mpg
i just prey this is a fault

ok befor you go running out to buy one start it up unplug mas it just pulls out go back and smell it give it a few mins lets know
