[Shotimes] 91 overheats in traffic

It's the T-Stat I just went through this is my both my 90 and 91. Matter of fact the T-Stat failed closed in the 90 and I ended up splitting the side tank. I ended up replacing the radiator T-Stat water pump. And I figured while I as there I would do the front 60K on it with cam seals. Got kinda costly. But if you pull the radiator cap off and you can see it suck the water down pump good. What was happening with mine was it would run pretty cool at 70-120MPH but stop and go it started to climb. With the T-Stat failed closed It would not circulate the water but the air coming in was enough to keep what water that was moving cool. 
I can't remember the brand but I picked it up at a Murray's discount auto 192 Degree with a Pair of giggle valves. 11 bucks

My 94 never had overheating problems, but when I pulled the rad to re-crimp
the ends I found a layer of dust and stuff that almost looked like a fine
fur impeading the airflow before the radiator. Cleaned it out with a hose
and it ran a lot cooler all the time. Perhaps there is something in there
impeading the airflow thru the rad even with the fan running.

My 91 overheats (or comes close) when driven in stop-and-go traffic. I've
confirmed it's full of coolant, burped the system, and the fan comes on
during a KOEO test. Even when I put the EATC in Max AC (which is supposed
to turn on the radiator fan), temp goes up when sitting still.

This SHO has 150K, new radiator and ECT a year ago, new water pump and hoses
three years (about 30K) ago. Recently flushed. The radiator fan is a used
unit, but it runs during KOEO. All in all, the cooling system should be
sound.

This car has a Ted Breaux chip and 73mm MAF. When the engine isn't
overheating, it runs like snot. I just mention this because the LPM can
choose a fan-on temp.
