Hi, Guys.
We had someone do a delete on one of our trucks. He also took of the twin turbo a put back on a single. After he got it done it all ran fine for about 15,000 miles. Now we have 2 codes showing up and 2 gauges stop working when the codes come on. Whenever it happens the oil and manifold pressure gauges stop working and the codes that show up are "Particulate Trap 1 Pressure and CGI Absolute Pressure."
Starting the truck and even running it at times everything works perfect, but at times out of the blue they start turning up.
