1999 volvo s70 misfire?? help :(
Well first off i have a 1999 s70 t5.
I was changing my oil today and after i was done my dad lightly sprayed off my engine with water.
after i started driving home i went about 5 miles with no problems at all, then it start to "misfire" and the check engine light came on blinking for a few seconds then just stayed on. I parked it and waited like 30 mins (car turned off) and started it again and it was still misfiring and the check engine light was still solid..
i read up on this and i'm thinking its a cracked/bad coil???
what else could it be, or what should i try to fix first to solve this issue?
- also i have been running 91 octane for the past few months and last night i just put back in 87 octane, not that it should have anything to do with this problem ..?
Please, the sooner someone could help me the better!
Thanks in advance!!!!!

+1 on pulling the codes. That will tell you which cylinder is missing. Also, once you know that one, you can un-plug it and re-connect it, that may clear the code if water made it loose just a little bit of it's connection. Water & old cars don't juve well in electrical parts. Every once in a while I just unplug & plug things back in to give it a fresh connection.
Try to be careful when washing down the motor. I washed my 850 motor and the next day I found a LOT of water in my spark plug holes. I didn't even think I sprayed that much water on the top of my motor but I had to pull each spark plug cover and dry them out with paper towels.

There is one but i guess it is against the law in CA for them to loan the tool out to people, so looks like i'm going to have to buy one..
