my newly aquired my95 uk turbo is absolutely crap on fuel. struggling to get 190 miles out of a full tank, compared to my 220-260 out of my previous MY98 wagon.

this new 95 uk has full de-cat and smells quite strong of fuel on start up and tick over. is this due to the de-cat? it also has a VTA dump valve in place, but i have the standard one in the garage. do these add to fuel changes?

overall, the car feels slower and less reponsive than my 244 bhp wagon and I need to know if anyone has any ideas please. (the wagon had just backbox and induction kit)

oi you lot, stop replying to ****e threads like "is the scoob becoming a boy racers car?" and help me out with a real problem!!!!!!!! pretty please

funny you say that. deamondave said mine stunk of fuel when i started it today. and my fuel don't go far.

 

The lambda sesnor would be a good place to start, the car uses this to fuel when under normal driving conditions. They do go, and when they do the ecu sees a lean air to fuel mixture, thus the ecufuels more than it should.

Aside from poor economy, you'll also find that at the lower rev range the car will feel under powered and quite lumpy, this should disappear at higher rev ranges when the car's on song.

You may also get popping from your exhaust when trundling along.

 

Oh and just to add, neither the VTA nor the decat should have any real affect on economy. (Unless the VTA is leaking)

 

Zhastaph, cheers for that. I believe i can get a check done on the lambda sensor if memory serves me right. also, yes, a bit lumpy at low revs, but once going it feels ok. I imagined the amount of pops and bangs i get cruising was due to the decat and blitz back box.

sounds the same as mine as well

V5 man thanks for bring this up
Zhastaph you have solved two peeps problems.


cheers

 

I used to get 250 odd before decat now less than 200. I think that may be the problem

 

...it's because red cars go faster therefore they use more fuel...

 

That`ll be it then Pele
Thanks for that!! wish it were true, but my old green wagon with 2 cats in place was sure faster than my new red one

If the car is poping and banging alot it could be the Dump valve. I had this when i changed to a blitz dump valve and the car became heavy on fuel and poped and banged even when cruising... changed back to standard and its all fine (i also have a full decat exhaust)
Let us know how things go...

 

Cliff - the green one was just too good to have sold ..... now you're going to be eaten by the new shapers' - again!

Give me a bell
