    1.It's right after the temp goes up. As soon as I tap the gas, it stays at 1grand then goes back down after 2minutes. Has no hesitation, runs good, just having the problem with the idle.

      Sounds like you need to adjust your base idle.
      Is the air condition on or off?
      Heater fan on or off?
      Headlights on off?

      If any of these are on the computer bumps the base idle up a few hundred rpm.

            Cars idle high on start up to warm up quicker (on hondas its called a fast idle thermo valve or FITV, the IACV also plays a roll as well)...also, the base idle should be able to be adjusted via a screw on the throttle body, at least that's from my experience.

                It does it repeatedly, even after it's warmed up, normal idle for a car should be about 1grand, not like 0. Right when I get off the gas, it sits at 1grand then goes down close to zero. Warmed up or not. I dont wanna fuck around with the idle by myself cuz I dont know what I'm doing so I'm mostly likely gonna pay outta my azz to have someone look at it.

                  This screw, with all accessories off. Should be 800 RPM. :icon_geek:
