Williams started using excessive Fuel

[Tucks]

.....It doesnt appear to be leaking out anywhere,but its drinking it like never before! Not getting 200 miles out of a tank,and thats driving as gentle as I can. Is it just likely to be the service parts(plugs/leads/timing sensor/Cap?),things that I can sort myself.Or is there anything else? It has the CAT in and is Standard.

lambda?

 

[edde]

Check the spark plugs see whats happening.

 

[Fred@BTM]

the first thing i'd check would be the pipe running to the map sensor

 

[Tucks]

Il find and have a look at that pipe tomorrow then,and allso cast my eye underneath at the exhaust/Lambda.
A new set of plugs wont hurt it I was thinking anyway so that too.
Cheers for the replys lads.

 

[Josh@Renparts]

is there anything to suggest it might be running rich?

 

[Dan@SJM]

Lambda sensor or CTS on the f7 series mate.

Its as flat as a pancake ATM so somthings not rite.

With the Lambda..can I tell if its knackered just by looking at it? Or do I need to take the car to a Garage for a exhaust test or somthing?

 

[Dan@SJM]

you can tell by putting a multimeter on it and testing the voltage, it should vary...
i.e 12.7-12.4v or something like that!! cant remember off the top of me head...

ive got spares of every sensor if you want to borrw them mate.

Symptoms if a fucked lamba are when its cold and idling revs dip down and then pick up again, and when you drive it it will kangaroo, and then sorts itself when warm.

Try unplugging the battery for a few hours, reset the ECU

 

[Tucks]

Sounds like it could be the Lambda then guys....it does the rev dropping thing when i first start the car for 5 minutes or so.
Il get on the case........

 

[Dan@SJM]

as abopve, ive got a spare lambda if you want to try it with out spending mega bucks on a new one.
