ECU Fiat Punto

Hi all, some help would be appreciated

I have a Fiat and recently the exhaust pipe broke from the middle (near the filter of silencer) I left it running without changing it and then I went abroad for 2 weeks and I left it parked and disconnected the battery (I think causing the ECU to reset) then after

3 days or so, the Engine is running half the speed, jurking and missing (it?s working only on two spark plugs)

Could there be a sensor in the silencer that caused the ECU to function at half the power or it?s more likely that the ECU is damaged ?

If it?s a sensor, Could I disable it and reset the ECU and see if it works?

Pls help

Thanks

How do you know it's only working on two plugs; if you are sure then maybe they should be looked at first.

have the ignition coils checked; failure is frequent with the Punto.
