Furling Issues

[stuart1298 6]

Looks like I have a furling issue, its over fueling on cylinders 2 and 3 but fine on cylinders 1 and 4, running standard ECU not chipped or anything, any ideas what could cause this?

[Daviewonder 533 3 Cars]

Try swapping injectors 2 and 3 with 1 and 4 and see if the overfueling follows the injectors.

[stuart1298 6]

That was on my lost of things to do.plugs, bed actuator, re do boost pipes as one popped off, boost controller to name a few off the top of my head

 

Sorry about the spelling, poxy predictive text on my iphone

[stuart1298 6]

right, local garage had a rolling road in there today, so took the 205 in there, and some very BAD results, 97bhp, not good for a 2.0 8v turbo, the 1.6 had more power

 

looks like i have a servre over fueling problem, i no i had onw, but not to this extend,

[welshpug 1,661]

should be easy to sort, are you on the standard injectors fuel pressure regulator and have you replaced the green ecu temperature sensor?

[stuart1298 6]

yup, new coolant sensor, new lambda, all standard,

[welshpug 1,661]

lambda isnt used on WOT anyway, wiring checked and compression tested? timing correct?

[stuart1298 6]

WOT? timing and compression been checked by a garage and all is ok

[welshpug 1,661]

WideOpenThrottle.

 

has to be wiring or map sensor then if the rest is ok.

[stuart1298 6]

map sensors in the bloody ecu, so would mean an ECU i assume??

[welshpug 1,661]

I believe it is possible to replace it, do vaugely remember a cosworth 3 bar item being mentioned.

I would be very surprised if the ecu had failed. Daviewonders idea would be first on my list. Fault finding is always a process of elimination. Overfuelling across all cylinders would be lambda sensor.

[stuart1298 6]

its constand overfueling, even on tick over, swapping injectors wouldnt make a difference, been told to try fuel pressure regulator

[jonnyturbo 3]

i have same problem yet mines undriveable as it bogs and backfires/cuts out once warm, i have tried 2 ecu's and 2 tps's cts lamba coil pack leads plugs ignition module, surely all arent broken? what in the wiring could cause it to overfuel? anything else cause it to over fuel?

[stuart1298 6]

it doent idle well atall, just seems to cut out, so have to keep the revs up, just spoke to one of my mechanics, he seems to think it might be an problem, and the reason its showing up fuel is due to lack of air, so my take air filter and pipes off from the turbo, and take it for a spin, and hope i dont get a stone through the vanes, also could be timings a tooth out,

[jonnyturbo 3]

id probli go for timing is out on yours, if your timing belt has timing lines on it line it up with the marks on the cam and crank pulley

[stuart1298 6]

i timed it up with the timing marks, and had someone check it, so i dunno, for it to be so far out i have no idea

err... Ok...

you said it was fine on 2 of the cylinders. You can check this by looking at the plugs

[stuart1298 6]

when my mate looked at the plugs he said 2 and 3, but looking at that print out, its got so much over fueling its gotta be all cylinders i assume, aint take the plugs out yet today, as it was a little warm, gonna have em out tomorrow, and check a few other things

[jonnyturbo 3]

take the plugs out check them all see what there like.

[stuart1298 6]

Gonna try that tomorrow, and will post pics up, got someone coming to check the timing for me tomorrow (hopefully) I'm sorta hoping the timings a tooth out, then it's an easy fix, fingers crossed

out of curiosity, does it still have a cat on it?

[stuart1298 6]

No, cats gone, but I've looking on the service box, my car hasn't got a knock sensor on it, gonna order one up, think this may be my problem

[Mark Greenwood 0]

interesting,, i think if the knock sensor goes O/C it retards the ignition

[stuart1298 6]

It should have one, would explain the left over plugs, gotta wait a few days for it to turn up. But the fuelings so screwed it could well be the knock sensor putting the timing out
