Just dropped a new 2.3 into my 2010 on my first start one of the fuel injectors was stuck open the truck had a horrible shake at idle that would almost disappear at 1500 rpm, the cat was blood red after 2 minutes of idling so i knew it was getting to much fuel, i found the faulty injector tonight and replaced it. The shaking is now better but still there. The truck seemed to be running good aside from my loud leaky exhaust so i decided to take it for a run around the block as soon as the motor had any strain on it the truck would sputter and bog with very little power would barley move and stall on a 20% grade. i wasn’t able to get over 60kmh on the level ground. Also whenever i stop giving it gas and try to come to a stop it will stall out but it will start right back up. Its not throwing any codes, anyone have any ideas on the issue? the motor ran flawlessly while in the donor truck
