Hey everyone...I have a 99 f 150 with a 4.2 V6....any tricks or shortcuts to replacing the injectors?? Intake has to come off too?
Thanks for any suggestions

If you have a bad injector, you should really get all 6 cleaned and flow matched. I have died replacing just one injector before, the problem is all of hem have the same mileage and same wear and tear, and if the old ones are partly plugged or don' have a good spray pattern, you get uneven cylinders, and that can cause new problems.

Yes, that is a good idea....makes sense to do all 6....just wondering how time consuming it will be.
