weird question?
so im driving home from dinner with my family last night. going a constant 71 on the highway. headin to my town to see my girls family
about 10 miles into my highway driving i let off the gas. i had been going a constant 71 for 10 miles just to see if i could keep it that steady. and the car doesnt slow down lke it should. the RPMs are the same as when my foot was on the pedal, the boost guage is right were it should of been for 71mph and i drove @ 71 mph for another five-ten miles. this struck me as odd, i dont have cruise control. i immediatley called my dad and he said it was weird and didnt know waht to say.
i then hit my break, and the car slowed naturally, like it should have the first time i let off the gas. now my quesiton... is the car smart enough to know i was on the highway and to keep that speed? or was it just somethign strange that happened?
this is a serious post. and its not because i was on a flat stretch of road. it wasnt completely flat. anyone else notice this eveR?

i was going to say cruise but cold temps could have caused the throttle to stick in that position then just by fluke it unstuck when you hit the break

i do this all the time with my 88 to save gas. i go at 70mph for a while then take my foot off the gas and just coast at about 70-68 mph for a while.. the weight of the car pulls me..

Moved to the 92-99 folder because this is a mechanical issue...any chance you accidentally turned on the cruise control? When you let off the gas, the rpm'* should decrease and the car should slowly decelerate. These cars will coast longer and decelerate slower than smaller cars...but if the rpm'* and speed stayed the same for 5 miles...then no, that is not normal.
