At 160K miles, finding carbon buildup in an engine would not be surprising.
Is it fuel injected or carburetor? If it's a carb, that's what needs attention, as the mixture is off. Either way, throwing a can of fuel injector cleaner into the gas tank wouldn't hurt, and it might help.

Air filter is clean and so is our air (I live on an island in the Pacific Northwest).
The car has throttle body injection.
I got the car a couple of years ago, it had a burned valve.
I took the head off, cleaned out any carbon in the EGR passages, head was in great shape. Plugs look fine mixturewise (tan).
Idle is fine, fast idle is perfect when started, starts in hot and cold weather.
Most driving is in light traffic 35 to 50 mph.
I work at home, so the car has only had about 5k miles on it in 2 years.
Drivability is great, just a BLACK FURRY tailpipe.
I've seen others of the same year with RUSTY pipes.
I just got back from draining the coolant, checking the vacuum hoses and EGR valve and throttlebody coolant passages. All are OK.
Thanks.
