I have 2001 dakota with a v6 and automatic. When you first start it up its ok, then drive a bit stop and turn it off. When you restart it, it runs rough and when you go it has no power and shakes and backfires through the throtle. Then stomp the gas so that it jumps into passing gear let off and it will run fine till the next time you turn it off. Then it starts all over again. It has no codes or lights. I had it scanned and got no codes. It has the following items new - coil, wires, cap, rotor, plugs, tps, both upper o2 sensors. Really need it to run good having to use it for work and don't have alot of work to be able to take to a garage or throw new sensors all over it. Thanks

 

read what i wrote #4 on post 'missing on six cylinders' all ways check the easiest and cheapest things first

 

I posted and idea I had on O2 sensor swap and I think it worked. I think the O2 sensor I replaced with a Bosch sensor from autozone was causing the problem. I had changed the left one to just see and no change, so I used the one removed from the left to try on the right and the problem went away. Had to make some mods to get it to work but had to try. Looks like Bosch O2 sensor no good for Dodge v6 like everyone has posted. Now to fix the shifting problem in the trans just got to get the money for the moduals
