hi, 2001 punto go 1.2 8v. occasional misfire when starting up from cold. engine light comes on with code p0351 ignition coils. car has new plugs, leads and new coils fitted. suspected head gasket but no coolant or oil loss evident. any ideas? car has done 76000m and seems to drive fine with good economy.

Compression test. But the code might indicate an issue with the LT side of the coil circuit, so check the wiring to the coil connectors from the loom, grease up the connectors themselves with silicone grease or vaseline.

I just wonder if there is a minor earth issue. Try a cold start with a single jumplead from battery -ive to the coilpack holder bracket..

cheers fingers. gonna borrow compression tester today, and check wiring. will let you know results

Hi, if the compression test shows no faults you should check all the wiring from the coil packs to the ECU on the top of the throttle body, if theyre all ok then it could be a fault with the ECU itself because they are quite common to fail, hope this is helpful, goodluck!!
