YOu might want to replace the sonsors tyou say you cleaned like the IMAP and others if you haven't. They read incorrectly when they get old or have been clogged up and never throw faults. It throw everything out of whack and causes soot problems. Make sure to do all the things mentioned here, like pressurizing the whole engine and checking it for boost, egr, and exhaust manifold leaks, etc...
