thick black smoke upon cold start?
Hi everyone, recently ive ordered new parts for my truck sct tuner exhaust ect. But recently i have been noticing that the truck has been startong a little rough. It always starts and runs good but its been blowing some serious smoke out the exhuast. A few time the code for the number 5 cyclander compression contribution has come on but once the truck starts and idles its fine. Im just wondering if i have a bad injector or if i should have someone take a look at it. Its. 2004 f350 6.0 drw lariat if that helps. Im having the oil pan, motor mounts, tranny line, and all of the gaskets replaced in the next couple of weeks anyway and im not sure if i should have them replace the injector or not. Any insight would be helpful.
