Hello,
My 2001 Mk2 1.2 8v 30k mile punto has been playing up recently.
If fails to start occasionally......turns over for a long time before firing.
Other times it starts first turn and runs fine.
The engine management light is on so I read the codes with KWP2000

Fault codes are as follows:-

P0201,202,203,204 Injector circuit Malfunction on all 4 cyl
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0351 Ignition Coil A Primary / Secondary Circuit Malfunction
P0352 Ignition Coil B Primary / Secondary Circuit Malfunction


I suspect the ECU is faulty but can someone concur ?
I read that the IAW 59F.M3 is a known problem but the faults decribed are misfires on 2 cylinders.....
Car has only covered 30K miles and I've owned it from new.

Any idea welcome before i start changing stuff out.

Thanks in advance.

Stu.
