I recently bought a 96 2wd with the 6.5 I have added a 3 inch exhaust and a better air intake system. I plugged the egr in the intake and put on a newer style turbo inlet with no egr valve on top. Life was good till it started getting cold. It starts very hard and the ses light will stay on. When I pull up the codes, they read like this: po251, po370, po406, and p1216. Switched out the pmd, same thing. As the day warms up, the ses light goes off, and everything is back to normal till a hard start and same old stuff the next morning. Any ideas?? Paul
