completely clueless on 91 eclipse
 

i have a 91 elcipse 2.0 non turbo dohc... when i started it cold it would run for about 10 -15 mins then just sputter then wont idle then just stall and it would have to sit for hours to start again..i replaced the temperature sending unit...then it would run for an hour or two then do the same thing...start sputtering real bad after it was warm n runnin then it would get worse n worse til it stalled...and stalled again...but since i replaced it, it only has to sit for like 5-10-15 mins b4 it will idle and run smoothly again..but then it goes right back to the sputtering after a cpl of miles....can ANYONE help?

Have you had the idle control valve checked?

Mine was doing the same... and that's what it was.

$250.00 at the dealer... ouch.
