TBI injector question

[my87Half-ton k5]

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

opposite side from the one the injector is mounted on.

 

[my87Half-ton k5]

but it couldnt possibly affect both sides? i mean if its stuck open? on both sides my plugs were black

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

ok i checked the front two spark plugs on both sides of the motor those are black which injector would that be

 

[neverendingproject]

you mean 1 and two or the first two on one side?

 

[my87Half-ton k5]

i mean the two spark plugs on the left and the right sides of the front of the motor...totalling four plugs...two on the left two on the right..which injector runs those plugs

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.
