99 forester, a/t , last few years during cold weather ,after it warms alittle , seems slughish , during warmer weather fine, thinking coolant termp, ? are all coolant temp sensors the same for 2.5 or different ? ,thanks

Yea, I am thinking the same thing. Replace the coolant temperature sensor may fix the problem. If not, you are not out much time or money doing this work.

 

I don't know if all 2.5 temp sensors are the same.

ok, thanks kinda hard to get to , but yes,
