Volvo S60 T5 2001 - Cold Start Misfire. P0300, P0301 P0303 P0304. - ScoBro

Hi

Was wondering if anyone has come across the same problem, only started happening today. When starting from cold, i'm getting a misfire off multiple cylinders.

I'll try the plugs first as they are a cheap and easy thing to do, and give the intake system a once over.

Heard something about PCV's being blocked and may cause a problem but these look light a nightmare to get to?

EML light comes on and shows Cylinders 1,3 and 4 , misfire. and P0300 shows multiple cylinder misfire.

Thanks
