A friend has a 2006 Chrysler Town and Country. Upon stepping on the gas from a stop the engine stutters, but when speeding up slowly from stop he is able to get up to speed without the engine having that stutter. There are no codes showing up. He had new plugs, wires, and a coil installed but the problem remains. Any ideas? I thought maybe the crankshaft positioning sensor, but i would think a code would be present.

 

Rarely get a code with crank sensor and anyway it gives problems as it heats up. Sounds like fueling/air sensor.
