Rough Idle, smell of gas in exhaust, less power than normal... water in gas seems wrong diagnosis

Thanks for all of the feedback guys. I’m bringing it in tomorrow.

@oldtimer 11, plugs and wires haven’t been changed for a while.

@mleich, light is on but I don’t have an OBDII adapter so I’ll see what the garage says.

I’ll update this thread with the outcome. In the meantime I take it that you guys think this is a relatively simple fix? Anyone want to wager on what it’ll turn out to be?

Update (sorry oldtimer, can’t figure out how to call you out here. Tried @oldtimer%2011, @oldtimer_11, quotes, everything.) Anyone know how this works?
