I have a 2006 Pacifica that "surges" or kinda "lunges" maybe. It only when the car is just cruising at speeds from 25 to about 40 MPH. If the car is accelerating it's fine. Thought it was a trans problem . had the fluid changed. No help. It shows no codes either. I was told it very well could be a throttle position sensor problem and a dirty throttle body. Any ideas ? Thanks...

 

I dealt with my surging by changing the EGR valve. Check this thread out:

Thanks.... that's certainly something I'll check out.

 

FYI for anyone that wants to know. I finally got it fixed. Carbon in the throttle body. I cleaned it. But it actually was a bad throttle position sensor. Found out that in some cases the sensor can have "rough" places that cause problems but the computer won't pick it up to give a code. Hope this helps someone else. God Bless everyone !

 

I had that surging problem changed the alternator fixed it
