    Ok, I am getting the following codes from my 87.
    24,43,and 44. Can someone help me to fix these. The main problem I am having is an extremely rough idle and sometimes stalling. /forums/images/icons/confused.gif

    Ok, code 24 is Vehicle Speed Sensor Fault
    code 43 is Electronic Sparck Control Bypass or Failure
    code 44 is Lean exhaust mixture indicated.
    Hope that helps, If you have access to a laptop you might want to check out WinAlDl, just do a search for it on google and the site will come up.

    It doesn't smoke at all.......Actually it runs fine with lots of power when I am on the gas, it just doesn't idle good.

    MW2 uses "Idle Flag" and "High Bat Voltage"
    MWAF1 uses "Clear Flood Flag" TBI data streams

    READ DATA ON PIN "E" OF ALDL CONNECTOR
