Did some driving around today and got stuck in the "Austin Parking lot" traffic. My water temp went up to about 227 on the digital so I turned both fans on (manual switch installed for both fans) and the temp came right down. Did this several times. The temp was going down to about 205 and then after a while of very slow driving she started to idle roughly and had a stumble on take off. Made a couple of stops and afterward she drove fine with no rough idle and no stumble. Coolant level is fine, no leaks. The radiator was flushed little over a year ago and temps while driving run about 198, but in stopped bumper to pumer traffic temps do climb to high 220's but the fans bring it right down. BTW she is a '94. Any ideas?[/align]

 

when was the last time you replaced your fuel filter?

 

How about your thermostat?
