Today I washed my engine off pretty good, and not loong after driving home it started to run real rough, at idle it feel like it's missfiring, and also when trying to accelerate. I've had a similar problem on my 87 runner, but that was just a wet distributor, I have no idea what to do with this 3.4 v6 because I have no clue what is going on with the wires. Also the check engine light came on but i don't have a decoder to find out which code it is. I'm affraid to drive to work with it running so bad, so any help will be greatly appreciated thanks!!
