Post Recurring P0344 - 2003 Dodge Caravan 2.4L

Total loss here: I keep getting P0344, shows with other DTC's at times. JUST completed repairs for P0068 which also displayed P0344. Replaced cam sensor (2nd time), MAP sensor, and TPS. Also completed a full troubleshoot of P0068 for integrity of vacuum (no leaks), removed/cleaned throttle body and installed with new gasket. Replaced intake manifold gasket. MAP sensor reads 10.9" hg (normal) KOER idle. TPS reads 13.5 KOEO. Plugs, wires, ignition coil all new.

The symptoms are the same: engine poor performance, lack of acceleration power. Can shut off, restart, and symptom disappears temporarily, then returns. Symptom does not present itself until fully warmed.

Anyone who has a pointer, or piece of advice, PLEASE let me in on it. Using Mac TaskPlus ET1205AN to communicate with vehicle.

10.9" of vacuum is not normal at idle. What's the TPS voltage? What is the mileage? Do you have an EGR valve? What are the other DTCs that pop up?

The reading is barometric pressure in inches of mercury (10.9"). Manifold vacuum is 19 inches idling. No EGR valve. Code P0442 (Small Leak) has persisted.

After MUCH troubleshooting, I went for the camshaft sensor pigtail. The dealership snagged me for $46.00, and I had to assemble the weatherpack connector, but it appears to have been worth it. I doubted TWO new sensors could fail, after reviewing my history on it. SO, unless I post on this thread again, I'm calling it "fixed".
