Misfire on fiat punto and not the coil PAC?

Appart from the obvious spark plugs or ht leads, I have read on forums that there are problems with the ECU and this needs replacing. I would go to a Fiat dealer and see if you can get a trouble code.

Suspect the crank pos. sensor...There are ways to check them on the car....But I'm not going to write an article tonight..but search....you wont be disappointed. You will need a LED test light... $3 @ Radio Shack....and a neddle to pierce the wires at the ignition control module.
