I have a 2005 Dodg Grand Caravan SXT 3.8. My vqn runs great when cold after driving approx. 15mi. it begin to not want to accelerate. bucks and stutters. If you ease on up to speed its runs great until you try accelerating normally. Had a garage check it. They replaced Cam sensor and Crank sensor. Upstream O2 sensor also replaced. Codes P0340, P0344, P0032. Still same same issues and same codes.
You could have a short in the oxygen sensor wire. I had a crank sensor wire short a couple years ago and it had similar driveability symptoms and misfire codes.

You would need to measure the voltage between the positive and negative pins of the wire harness. I don't know all the details offhand like which pin is which and what the voltage is supposed to be.
Inspect the fuel injector harness on the rear cylinder head. That year may have shorted wires burnt inside the wrapping and you may have cut it open to inspect. The P0340 and P0344 maybe a cracked flex plate, That's just a guess.
