After finally replacing my ICP sensor, we threw the truck back together and cranked it up. Ran fine for the first day or two, then one morning, (about 55-60 degrees) i started it up and let it warm up for a few minutes, then i took off out the street and had no power when i tried to take off until it got to almost 2,000 rpm, the took off like a bat outta hell, and then i had a huge miss, and now at idle it has a roughness to it, and when i take off you can hear it sputter then go. Throwing a P0266 code and im hoping i wont have to sink more money into fixing another problem. (Truck has 182,xxx miles). Any way to check see if it is a failing injector?
