    Hey guys great site! I am about to lose it after working on my K5 for two weeks.
    1989 K5 350 TBI
    Starts and Idles but bogs on acceleration and is undrivable due to the stalling. It always starts right up and idles smooth..the thing bogs bad when give gas!
    Thinks I have done

    TBI GASKET
    Fuel Pressure Regulator
    PLUGS
    Wires
    Cap and Rotor
    Coolant Temp Sensor
    Checked Cat
    NEW Distributor, IGN Pick Up coil, IGN module
    Fuel Filter
    EGR seems to move
    Replaced Computer and had no change so took it back
    Am I forgetting or missing anything?
    Orginally I have had no codes..but now I have a code 22..but I think it is because I unplugged it last night. Any tips? Thanks and rock on!

    Sounds like the dist is off 180 degrees? Don't know much about TBI. But I messed up a distributor install once and it idled fine but with any load it'd stumble. Good Luck. Keep us informed

    The TPS (throttle position sensor) may be bad. Located on passenger side of the throttle body.
    If the computer does not see the throttle opening it wont give any gas = dies when opening throttle.
    Code 22 shows a problem TPS circut.
    It really helps to have a scanner when looking for these problems. it will save you a lot of money in the long run.
    Auto X Ray scanners are only 140 bucks its a lot cheaper than replacing parts till its fixed.
