I'm talking diesel rich, the pipes are black and you can visually see it rolling out the pipe with every spike of the throttle. I have seen my fuel trims at -17. Once it's warm it surges and wants to stall. I have replaced the o2, iac, maf and map sensors. I noticed a small header leak at cylinder #2 because the header wrap was getting sooty. It wasn't something that I could feel but I welded it up. The spark plugsan o2 were sooty. MThe idle seems normal. I doubt I have a vacuum leak as its all new hoses. I did spray the engine with carb cleaner ad seafoamed it and didn't turn up anything.
