My 98 Grand caravan sometimes has a problem when pressing the accelerator fast. Sometimes it will rev fine, and increasingly it will stumble, and not hit on all cylinders, like it is flooding or something, and when you let off the accelerator it runs fine again. If you ease into it it doesn't happen. It has died on my wife several times at stop lights, and does it on startup on occasion. The check engine light is not on. The timing belt, plug wires, and plugs are all new. Any clues on what to check? Cam sensor? MAP sensor TPS?? Thanks for any help. I cycled the key 3 times to get any codes, and there is a code 12.

edit: Also the engine is a 3.0 V6.
