Give OMEX a ring or email them. He may be able to shed some light on it.
If you could get someone to go online to the OMEX you can monitor the feedback from the sensors and should be able to see any problems.
But decatted how would this make much difference? I dont think with the way my decat is shaped the lambda's do anything. And surely this wouldnt account to it running on 2 cylinders?

a faulty lambda would cause poor running and apparent missfire most often about 30secs after a cold start when some of the other s**t that runs the car from cold, start close down (air bypass, fuel enrichment ect) also if you have recently fitted a decat it is most likely because they never finish these things nicely and leave swarf and s**t in them. this gets onto the sensor and f***s it
however philthy, the car should at least start even with a faulty lambda sensor. however you could try unplugging it and starting the car?? the ecu will think its faulty and resort to a generic reading. these readings usually err to the rich side too to be safe

Did you change the leads?
Another very long shot is a collapsed baffle in the exhaust.
Heard of this before on fiestas before.
Is it a new exhaust? Was it fitted using silicone jointing compound?
Apparently this kills lambda sensors stone dead!
Still sounds like electrical/sensor problem though.
Were the connectors on the tdc in good nick.
It might be worth chopping them out and soldering them.
Don't give up.
You'll feel like a star when you find the problem

I don't think it would stop it starting though, or make it run on 2.

Mine happens when the car is cold. Especially on wet mornings. After about ten minutes the problem dies away.
Any clues?

its FIXED!!!
it was the fuel cut off switch (red rubber top on it) which was broken, it wouldnt stay down. And also the white wiring loom next to the fuses was loose, which caused the fuel pump to be intermittant because of a bad connection.
something so simple as well, cant explain how happy i was when it started haha

Whats contact gel? How do i do that?
Is so annoying, as it could be so many things
want to put the car up for sale, but need to sort out what the problem is and fix it properly first.

Dan, just use wd-40 and let it dry then cover it in vaseline!

well i just took mine for a wee spin (5-10miles) and used quarter of a tank running on 2 cylinders most of the time....
im banging my head against the wall now.
dan, take the leads off the coil pack and spray them (one at a time so you dont lose where they went) and also the connector going into the coil pack

So, what have you changed?
Make a list and then see what is left, lol

Wiring loom fault?? broken/rubbed wire somewhere? but you could look for that forever!!!
Exige S1 + Honda S1
coilpack, sparks tdc sensor and soon to be leads
edit- the cars sits at 2k revs when idling now(when its on 4 cyl) its obv very running rich as it used quarter of a tank in 10 miles.
when sensors effect fuel? I know the lambda does, il disconnect that tomo to see if it helps
air temp sensor?

Coolant temp sensor does. Check the wiring to it and replace it. It enables the cold start map and if it is'nt working will tell the ECU it's always cold and throw loads of fuel in, hence the rich running.

I think so mate. Not 100% it's blue but it is above the TDC!

I have no idea how the OMEX loom works so I'll step away from the table

If it's fine in the cold but when it's up to temp hesitates and trys to cut out when you touch the throttle I'd go with coolant temp sensor.

Would'nt the OMEX just pick up the signal and act on it? Which sensor does it use? It's own or the Renault one? MAybe one has failed and is causing the OMEX to confuse itself.....
Nup, it stutters when cold for the first five mins, is fine after that.
the omex ecu uses the omex CTS (which as i said should be on the engine side of the thermostat, so it can adjust the fueling as the car warms up from cold)
the sensors have to be calibrated
this is done in the ecu settings, you first take an ambient air temp reading and enter this into the software (so thats you're baseline reading for the temp sensor to work from) then you put the sensor (connected to the loom) into a container of boiling water and then enter the temperature into the software

Have you had it plugged in Dan??
What would cause it to un-calibrate itself though Fred?
