    The car starts some times fine and in other times it starts and then
    dies if put in gear and then immediately starts with no problems in
    starting but when I push the accelerator the car's responce is slow it
    feels like it is doesn't want to go and it just takes a little while
    and then it just goes as if nothing happened.

    On a side note, the car had a problem with the NOx in the Emission
    testing. It got a 2.9 gm whereas it should have scored 2.5 gm or
    below. The car doesn't have an EGR valve so what should I check?

    The car doesn't have a check engine light so how to read the codes in
    the computer if there is any codes to help diagnose?

    '88 won't have any codes to read. First check for vacuum leaks, if you don't
    have any of those, suspect the air mass meter. Engine wiring harness may be
    shot as well, look for crumbling wires, they changed the insulation right
    around the year that car was made so it could have either.

    I just had something similar to this, and it was a fuel injector relay.

    For the Air leaks, is there a systematic way of checking for leaks
    other than using carb cleaning compressed can and spraying around
    vacuum lines?
    Can I visually know if the Air Mass Meter good or bad?
    I was told once before that this model car and year are not in the
    category that have a busted wiring harness.

    There's no visual test for an air mass meter, other than obvious damage.

    Most '88 had the updated wiring, a few early ones had the rotting harnesses.
