Every morning it is a little rough startin my truck. Once it's running and warms up through the first 30-45 driving it's smooth. As I'm driving and it shifts to top gear it starts having a little hump to it. Nothing to truely affect the driving. I just changed air filter and fuel filters. Don't know what else it could be or what I could do. Any help would be greatly appreciated. Thanks!
Injector stiction or failing injector. Search injector stiction and at treatment to your fuel. Without proper lubrication no amount of oil pressue will open those injectors. Theres a ton of other things that come into play in terms of fuel lubrication, proper oil flow to the injectors, leaks, etc. Start at square one and move from there....
