✨ GMC Yukon & CHEVY Tahoe Fuel Injector – DIY FIX ✨
How to remove and replace Fuel Injectors . 2004 GMC Yukon shown in video.
Try adding Seafoam gas treatment from AutoZone first.
New injectors are over 60.00 each.
This car showed cylinder number 3 causing a miss fire.
I removed the right side fuel rail and cleaned all for injectors and then reinstalled them. After cleaning the truck runs strong again. No misfires and no rough idle.
