so heres the deal i had my motor checked its a 5.3 liter
v8 and the #4 and #8 cylinders are firing way outa control im talkin 4 does 4000 misfires a minute and 8 does about half that
everything else is great
sencors are good
no vacumm leaks
and also my moto got hydro lock i beleive two of the injectors are bad ones probly shut wont work and the others stuck open
any ideals to check?> a very older wise man told me today to take a screw driver and stick the tip to the injector while its running and put my ear to the handle of the screw driver and see if i hear clicking if i dont the injectors bad?
any input?
thanks for your time people just another new dad with a daughter to provide for and i cant provide if my wheels keep messing up
