2002 volvos60 codes po301 po350 and po351
our volvo shows 3 engine codes po301 po350 and po351 which says ignition coil a primary/secondary circuit malfunction , cylinder/misfire detected would replacing the spark plug and coil /(rubber boot that goes over the spark plug) fix the car
All of the codes pinpoint that coil #1 is the problem. So replace the coils, boots and spark plugs of all 5. I suggest since your in doing the repair, replace all of them as I suspect the rest are soon to follow. It should take care of those codes.
