    After my engine warms up to normal temp.if i stop at a red light or stop sign my cars idle fluctuates from 700rpm to maybe 2000rpm up an down up and down any body no why? I cant figure it out the engine doesnt sputter or have any problems while driving

    Air leak in the intake system somewhere probably- check your gaskets.

    By the way, welcome to HondaSwap! :wave:

    check your (iac/ idle air contol valve) valve on the back of ur intake it could be bad or some dirt got in there.pull it off and clean the screen inside it.
