    i have an 87 350 tbi K-5: my question is this,
    if one injector is stuck open will it affect all 8 cylinders or just the side that the injector is mounted on?
    thanks

    It will affect two on one side and two on the other, at least on a stock manifold.

    Sure it will affect all of them...the O2 sensor will see the additional leftover fuel and try to compensate.

    As mentioned, the stock manifold doesn't simply feed 4 runners on one side and four on the other, they are mixed up. Someone here knows the pattern guaranteed. :)
