have you changed the coolant temp sensor? That alters fueling


Garage said "there near certain it aint that"

But suppose its just their word, and wont harm getting a new one, as im guessing they aint that expensive.


just get one dude they dont cost much and are easy to replace.

So it may not be the ECU :(

O man im near to giving up.

So Could be either

ECU
Air Coolent Temp
Or maybe timing hasnt been done properly?
Or something to do with the inlet manifold?
Or the K & N cone filter?

:(

luke, i send you the ecu and transponder chip tomorow, u2u me stuff, but i spoke to someone he doesnt think that a chiped ecu shouldnt do that though check inlet manifolds for leaks, possible look into changing coolant temp sensor

Cheers Bieran


any more advice would be good peeps! ;)

i'll get on to him tonite. and could pss get it too you help you out.

the timing could be a cause if the ignition timing is out it will be leaving alot of unburnt fuel. henc HC's and guzzling fuel.

cambelt yea, just wondering if the timing was out.

no problem homie. like i said try an ecu if you get hold of one. i'll ask a mate if he has one. you in telford?


So it could be that when the cambelt was changed and fixed, it wernt set up correctly?

And cheers dude! yeah im from Telford. just panicking & gutted abit now. as i cant move the car at all (no tax/mot) , and the garage have seemed to have given up too. :(

best option is ecu as its odd that all 3 are so high. specially HC seems like loads of fuel is there unburnt.

timing belt been done recently? timing correct?

edit: you say its thursty too so definetly overfuelling. id say you have a mccains chip in there somewhere

[Edited on 05-09-2008 by bieransri]


Yeah- crazily thirsty. like £10 to 50miles, and i drive like a granny.

Timing belt?, cambelt is that? if so it did snap 5months ago. and was replaced with the 2 bent valves straight away.

appreicate the response dude! :thumbs:

could be a 'chipped' ecu as will just make it overfuel. hence HC reading.

CO2 - misfiring at all?

both will cause lambda reading to be out,
id go with trying a standard ecu first. maybe ask someone to lend you one for the test?


Just finding someone that will lend me one is the problem :(

And misfiring? at odd times when started from cold, yes it did do this.

It aint anything to do with the Inlet manifold is it?

Or dodgy ECU? that may of been chipped?

Stuck what to do next :(

If code 94 comes up start crying :thumbs: Quad Drive module in the ECu or something.


and the car runs absolutly perfectly. no smoke/no problems etc. just a little thirsty.

and the ECU light has always come on, but never affected driving etc/ runs perfectly as said. the code which was diagnosed was to do with the lambada apparently. which has now been changed.

sooo confused :(

O because it was needed to fit the cat to the manifold. as i have a sports cat on at the moment and a new down pipe was needed

Or did you have a full system on it?

Ok, as some of you may know ive been having serious problems with emmisions.

At first --

CO2 - (max 0.50) Reading - 5.4%

Hc - (max - 200) reading - 547

Lambada - (0.97-1.03) reading - 1.25


Therefore i have purchased -

New Vaux lamba Sensor
New Standard Vaux Cat
Down pipe to fit Cat to manifold.
New valves etc

But just had a phone call to say its still a big fail, and the readings aint altered at all. :(

Now i aint got a clue what i should do now, the garage did however suggest that the ECU may be the problem, and did ask if it has been "chipped" i dont know. but may of done from the past owner.

So will a chipped ECU mess it up like this? hence me needing to plug another standard X16XE ECU in?

or any other suggestions. BIG help needed

Cheers. appreciate the help guys! :thumbs:
