I have a 07 Pacifica, everytime I go over about 60 mhp on the interstate for over 4+ miles and then come to a stop the car dies. I have taken it to our dealership they changed the throttle body for $350 and that didn't work. When the car dies the check engine light does not come on. Dodge also said that it doesn't throw any code. They say they have check everything and everything is working ok, any help would be great.

 

Sure sounds like a vacuum leak to me. Don't where, why or how, but the pro mechanics on this forum would be the ones to steer you in the right direction if thats the issue.

 

Check your Trans Fluid.....

Its possible after wngagement , your torque converter did not UNLOCK, which will stall the ebgine when coming to a stop.

HOW mNAY mILES ON THE CAR.??

 

It has 65,000 miles. There is nothing else wrong with it. I figured that Dodge would have checked the trans fluid. I asked them about the power brake vaccuum but they said they checked that.

 

After 6 trips, 11 days without car, 1 rental. I have a new throttle body,torch converter, and a new torch converter sensor. It finally was only the sensor. Anyone who buys this car needs the warranty. Im into repairs about $700 but without the warranty it would be around $4000.

 

Which sensor was it? If you can post the sensor name/type over here; it would help if anyone else has similar issue.

Most stalls while creating g-forces are cause by faulty wiring.
1 out of 4 of the bundles of wires going to computer did not fit into a plastic opening/bracket in frame so was routed between motor, motor mount and engine.
You can even think you fixed the problem sometimes (not saying in this case, of course I don't know), but it comes back until you pull the wire out onto the radiator support and solder the wires back together.
There will probably be a lot of damaged wires in there.

Also use a solid front (and back if you want) motor mount. It will last longer with a small amount of vibration increase if you only use a solid front.
Westar solid mount I bought from rock auto was not solid. I bought two. One had 3 more ounces by weight of oil in it than the other.
Then I bought one on an auction site that has 5 year warranty because I thought it might be solid and when I received it I was proven correct.
It was almost 1 lb heavier than the fully oil filled mount.
