Whats normal Injector readings

 

[Ron Nielson]

+4 to -4

Engine should be at operating temperature idling in park and on stock tune.

Is the number 6 injector good? Or working? It stays on 9.6 at all times when its idling. Never changes.

Engine up to operating temp should be +/-4 in park or +/-6 in gear, reading at an idle.
It’s a +9.6 that means it’s trying to add fuel so it’s likely that it’s somewhat clogged or restricted. Try running some heavy duty cleaner and some heavy throttle runs to see if it helps more than just temporarily
