I have a 98 V70 with 215000 miles on it. I just replaced the spark plugs over the weekend. This morning went off the road in a ditch due to snow. My problem is since then my cel is on and flashing. I pulled the codes and recieved six of them.
p0302 -cylinder 2 misfire
p0301-cylinder 1 misfire
p0300-random cylinder misfire
p0116-engine coolant temp/range
p-0442-evap emission control system leak
p-0410- secondary air injection system malfunction.

Car is running like crap right now. I am wondering if it is due to something that happened when I changed the plugs or my rear end going into a ditch this morning. Is this a coil issue or did water get somewhere it isn't suppose to. Any advice would be great thanks.
