I have been noticing that while trying to get up to speed on the freeway, the turbo pressure will drop to nothing, then jump around and finally max out with a large air gush sound from under the hood. Then it seems to clear up and run fine. Only seems to act up when under load. Checked for codes, nothing new, only the p0401 that I have had since the EGR delete last year. This morning I had my trailer and could barely pull it, no power. Checked for codes, had the p0401, along with p0299, 0046, 0069. Anyone have any ideas? I cleaned the turbo last year when installing the EGR delete. Would it get that bad in a year? I want to get an idea of what to look at before I start tearing into it. Don't want to remove the turbo again if I don't need to.
Also, I am looking to buy a new code reader, something better than the $50 basic unit that I have. Any suggestions?
