Hi Guys & Girls,
I have a problem with my mondeo, yesterday it suddenly started to fire on only 2 pots (1&4).
I thought it was the coil pack so removed and fitted it to a friends mondy, the result, fires all 4 pots.
After much research, i need to know if it is right that the ECU has failed.
If it has, do i need the exact same (NECK) ECU? I did try another (BASH) but it didnt even turn over let alone fire.

Thank you in advance for any help and/or advice.
