Hi all,
Long time lurker here and have found the info on this site invaluable in the past however I've hit a problem and really stumped.
I have a mk2b 16v Punto. It's throwing p0300 301 303 as well as p0480, u1600 and 602. For the misfire codes I have tried the usual new ignition coil, changing the HT leads, sparks. Even tried a virginised ECU. Whatever leads I use on 1 & 3 cylinder the fault remains, but the sparks are showing strong sparks which makes me think that it could possible be the injectors.
Does anyone have any ideas what this might be and whether it could be the injectors? Cylinders 2 & 4 are completely fine. My only other thoughts is that it could be something related to the control sequence for the injector timing, can anyone advise what might control this, i.e. could it be crank/cam sensor related, or purely ECU?
Thank you for your help in advance!
Cal
