Recently I have been having extended crank and very rough running for about 10 sec after sitting overnight. If I drain fuel bowl it will start OK for a couple days than back to hard cold start. Also on way home from 150 mile trip truck started to have miss for about a mile blew a lot of smoke(could barely see headlights behind me) pulled over and engine was running very rough than as it idled started to sound normal after about 10 seconds drained fuel bowl and drove the last 3 miles home fine. Stuck injector? Or any other ideas
Has f1 90 up injectors remans about 3 years old but only about 15000 miles on them


Thanks josh
