i have a 1994 honda civic hatch with a 1996 acura integra ls motor swap. Before the swap my heater worked amazing like i would sweat in my car but now it dosnt work all hoses are hot, and running the water. i have flushed it taken it apart and yea still nothing. its freezing cold out and i need it... next is my idle hops up and down from 1000 to 2000 it comes and goes with whatever mood its in. it does it when its warm and cold and is highly annoying cause it will go on its own then lay back then jump again. normally takes roughly 3 to 5 seconds to jump idle again. any help would be much appriciated. thankyou.
