Thanks for the info, i think i may have miss informed u or something,
The engine came from a donar vehicle and was runnning before it went into our vehicle i havent split the block and head, although i will still try this but i feel it wont work.
Also i have noticed when its idleing that the red backlight on the lcd screen between the speedo/ rev counter is pulsating too so it suggested to me a bad earth, but i have checked all the earths are secure, i have even removed all the wiring from the engine, ecu etc etc to see if i could find a bad connection and still nothing.
Any other ideas.
Do you know anything about the fiatecuscan and the actuation of the lambda sensor replay?
