Hey scotty, I have a 2010 dodge avenger that is having random multiple misfires. I have already replaced all spark plugs and ignition coils plus camshaft and crankshaft sensors that were bad according to a scanner. After all of this my vehicle is still showing random multiple misfires on a scanner. Any idea on what the problem could be?

blowing head gaskets are common. check that first Also check for dirty fuel injectors or weak fuel pump
