Hi guys,
Can anyone help me with this code,I know it's something about injector 4,but I'm not sure is it injector or injector harness... Thank you
Sorry I forgot to mention most important thing...
Truck runs smoothly,and when I get to up hill or some bump on a road,I'm hauling 48,000, I get check engine for injector 4 and engine starts rumbling and shaking,then I stop turn off the engine wait 2-3 mins,start it again and it runs normal,any suggestions?
