My ford f-150 ecoboost 3.5L V6 started out of nowhere to not turnover right away when cold starting. Then when did start the rpms idle was at 1400 should be at 700. Then the engine would make a shuddering/clunking sound for about 10 seconds then stop. Truck would not accelerate quickly took about 20 seconds to go from 0-30 mph. Turns out I had a fuel injector leaking. Conveniently the extended warranty I purchased only 5 months ago when I bought the truck did not cover this. I had also taken it to the dealership I bought it from two days before hand to get an oil change and described the starting problem and they apparently could not find anything wrong. It is a hassle and I have only had the truck for 5 months.
