After about a week of doing nothing it all, it ran like it normally does (with the exception of the gasoline still smelling a bit rich.)
no black smoke. no power loss. Just a low idle.

Reset the ecu and we replaced the fuel filter. The filter we replaced was completely full of junk (Again).
Apparently my gas tank is full of crap.

The ticking noise is gone.
I'm gonna keep driving it around to see if it happens again...
I'll keep you all posted.

Question: Do you remember the weather when it started acting up? reason I ask, I've just decided the mis-fire I'm getting periodically in my truck is rain related. I'm thinking I have a stopped-up drain below my windshield that is allowing rain water to overflow, filling the spark-plug well with water, and drowning out that plug wire. That misfire results in heavy gas smell in the exhaust, bad gas mileage, rough running. But several days later, with dry weather, it straightens up completely.

Possible you are having something similar??
