Hey y'all! I've had a recent problem come up with my SR5, yr:1990, miles 265k. Anyway within the last week of driving I've noticed a problem arise with my idle dying down to to 250-0 rpm. This only occurs after I have been driving highway speeds and then going down into town speeds. When I start up in the morning and drive within town to work there isn't a problem and my idle stays around 850... Even after I've been driving in town and engine is warm the idle is fine. So I'm seeing a correlation with high speed and then the low idle follows. I'm suspecting a problem with the cooling system and possibly a clogged line, therefor stealing power from the engine...

I would like some expert advice as I am not...

Lemme know what y'all think!

Sounds like a bad injector or a vacuum leak of some kind. I would reccomend checking those and also cleaning your throttle body and replacing your air filter as well.
