Took mine to the shop for the fuel system eval yesterday and got mixed results. The injectors seem to be functioning properly, but the fuel pump is at the top of its operating threshold. They opened a "STAR" case so now I'll pull up a chair next to you and wait patiently to hear what they say. In other news, on my way home my truck went into a regen within 5 miles of leaving the dealership and 67 miles after the last regen that occurred during the morning trip to the dealership. It threw a CEL that I'm sure is the P2459 code. Oh, and they pulled off about 3 qts of oil because it was a couple over when I got there. I had the oil swapped out, again, last week and only made one short, in-town trip and then the 120 mile mountain road trip to the shop towing my Jeep.
