hello, i own a 1999 dodge dakota r/t. which developed a knock and spun a bearing. brand new engine in. all done correctly. and its running really rough? there is a knocking that sounds like the distributor. but we replaced it and it did not help. the truck coughs when you try to give it gas. misfiring. its a knock. but it cannot be the new engine! could it be a sensor? before we pulled the old motor. it threw knock sensor codes. but its not throwing ANY now. help!
