i was driving down a two lane road tonight and the road had standing water all the way across it for about 100ft and i had no where to go so i trucked it and i got threw it and then the car started spitting and spuddering real bad and shut off. car cranked right up but idled bad and when i revd it it sounded horrible then died again. i pulled the intake tub off on the side of the road and it had some water in it. i managed to get a scan tool on it and it said misfire in cyl 8. i let it run for a little while then it started running a little better and i drove it around to see if it worked it out of the system for a little while. while on my way back home it started making a slite ticking noise. do you guys think i collapsed the plug? and the ticking noise could it be a valve tapping as the result? what do i need to do to check it or to fix it? thanks for the inputs.
