My 1993 caravan with 3.3 liters runs rough for about 1 mile then no problem. As soon that the engine gets a bit hot no more problem.
If I accelerate slowly when cold no problem as soon as I go over approx. 2 000 rpm it runs rough. When I start it cold and still on the park position it runs rough when I push the accelerator. It acts like it is not getting gas. Once it is over 2000 rpm when cold, but after warm it runs perfect.
It seems to be worse in humid weather condition.
I tried changing the spark plug cables twice.I changed the map sensor.I have the codes 12 and 41 intermitently.I would really appreciate any help.
Thanks
