    H22A Injector Size

    Hi all im going through a process of trying to find out what is going wrong with my ride atm.

    First of all im looking for the specs for the Injector size required for the H22A.
    Secondly how it differs from the F22A.

    Some background info....
    Ive got a 1990 accord with a H22A swap, Magnecore spark leads, NGK platum spark plugs, DC sports creamic headders, Stock accord Airbox, 2.25" cat back ehhaust.

    My problem........
    Rough idle in the mornings the car will surge up and down the RPM range till it warms up.

    What ive done so far.......
    Ive cleaned the EGR valve, IAC Valve, Had a throttlebody clean, changed the fuel filter, cleaned the spark plugs.
    With the stuff i have im pretty sure it is not a spark problem.
    What i am thinking is that mabe its my injectors and one of two things.
    1. they arnt big enough
    2. they are not clean enough and are not atomising the fuel properly before spraying into the block.

    Can anyone tell me what size injectors the H22A should have.
    And can anyone give me a quick guide to removing the injectors for cleaning.

    Thanks....

    Obd1 h22a injectors are 345 cc. Check this thread out about solving your idle problem, I had the same problem with my H22 and I highly doubt it's your injectors http://www.cb7tuner.com/vbb/showthread.php?t=49714

      OK ill try that too thanks heaps.
      I too have bled the coolant sys after cleaning the IAC valve
      Checked for vac leaks.
      But i hant checked intake manifold gaskets, or checked the TPS voltage.
      What should the TPS voltage be?

      Question what is FITV?
      Fast Idle throttle body valve??

      And do you have a pic or tell me where its located

        JDM injectors are 345cc, but USDM has 310cc injectors... Food for thought.
