Lemmy; Because it happens at around 2300 RPM you may want to check that the IMRC actuator rod has not popped off the IMRC ball. It's at the back of the intake right next to the firewall and a real pain to see. A flashlight and inspection mirror will help. The IMRC kicks in around 2000-2300 RPM.

You might also want to check the two vacuum hoses coming out of the IMRC Solenoid. They will dry rot.

Even though it wasn't very old I took the coil off to look at it and found a hairline crack on the back. I took it in for a free replacement (still under warranty) and fixed the problem. I think with this truck any time you have hesitation or misses without a code I think the coil is the first place to look at the plug wires are probably the second. But the IMRC is definitely a good thing to check. I hadn't thought of that. The insert on the front popped out once and I replaced the intake, but I have never had the actuator rod pop off.
