    more problems arise

    Basic info:
    90' auto vert converted to 5spd.
    Just re built head.
    As far as i know the timing is spot on.

    The engine starts but the idle is quite erratic. Sounds almost like its carbed.

    When cold it tends to stall out at idle.

    When it stalls it wont start right back up first turn like it does on my first attempt to start. i must sit and let it crank for about 10-15 seconds before it starts again.

    At any temp it hesitates when i press the throttle until about 2,000 rpms.

    Ive already cleaned my ICV but im not sure how i can test it.

    I replaced the intake boot and checked other hoses and im pretty sure i dont have a vaccum leak.


    Another Strange this thats happening is that when at idle the parking brake, battery and brake lining lights glow dimly and seem to get brighter then dimmer with the same rhythm as my strange idle. how ever if i rev the engine the lights turn off.

    What in the world is going on with my baby!

    The only way you can be sure that there are no intake leaks is to have a shop run a smoke test. The symptoms described sound like intake leaks.

      Check your system voltage. Either your alternator is undercharging or your battery is marginal, and sometimes even both!

      Your ECU has a voltage offset table that can help compensate for low voltage but only to an extent. The pulsing of dash lights is a clue, but usually the ABS light comes on first.

        leak of air between #7 and #1 its just hisses when ever the car is running. It is some sort of vacuum hose?

            You probably need a new voltage regulator. Cheap and easy to replace.
