think it could be the o2 sensor..

If sensors have been changed for working items then start looking at the wiring loom.

Flash the codes of with a paperclip then start checking the loom at the sensors that fail.

Not a clue mate i couldn't diagnose it tbh

yeh it is the one from crew mate, so what do you guys think the problem could be then :boggle::boggle:

iirc that flashed up afm high voltage

if it is the car my mate sold

Mine used to do that, always flagged up the knock sensor and AFM when i flashed the codes.

if so

The CTS has been changed already
Tried numerous AFM's on it
Fuel pump relays
Not sura about fuel pumps though

Wouldn't happen to be a red sport with a gsi kit on from down crewe?

Mine was doing similar, I swapped the AFM and CTS and now it's fine.
Have you tried flashing the fault codes?

Hi i went out and bort a corsa c20xe on saterday, the day i got it was running fine no problems etc

Next day i decided to give it abit, after i did about 10 secounds later, it would bog.. and if you try to rev it just wont.. while this is hapening the engine managment light is coming on and of.

so i turned her of and started her back up and she was running fine..

Its done this a countless emount of times now, but now its even worse and im unable to use it.. as it does it every 20 seconds

Any ideas what this could be ?

Thank Ben.
