    in need of some $.02

    So recently when I get in 3-4k rmp my m20b27 slightly spits and sputters.
    I've only done 1 thing that I think might cause this and that was cleaning my icv with fuel injector cleaner.
    So I'm asking if an idle control vlave could cause that,or if it's something like a fuel deal im really unsure how to troubleshoot this one
    Thanks rev

    I doubt the ICV would cause that. The idle control valves does what the name implies controls the idle. Once you are going its not really doing much. More likely a miss. Check your plugs, wires, and distributor. Also try running some fuel system cleaner through the car.

      fuel pump. fuel pressure regulator, fuel filter.


      dude, the icv is for air, not fuel... I really hope you blew air through that icv before putting it back on and starting the car.

        many, many, MANY things can be the cause of hesitation for m20 motors. honestly, you could throw parts at it all day and not fix it, so i say take it to a mechanic and pay him the diagnostic cost so he can tell you whats wrong. at a minimum he could tell you which system is the stem (fuel, air, or spark) and you could go from there.

          I have spark,I have fuel I think I've put off a valve adjustment for to long and wore a lobe because once its warm It goes away,
          And i didnt blow air threw the icv,I didn't put that much in there I didn't want to destroy the internal plunger
