Problems with Pacifica

kalli11

Our 2006 Pacifica has been a good vehicle for 7 years. Has almost 200,000 miles. The past few months it is been shuddering and acting like it cuts out only in low rpms; but it has never stalled. We've had the 02 sensors replaced and the wiring replaced around it. The fuel tank also cuts out every few gallons. The mechanic now thinks it's a wiring issue. He says the transmission is good. What should we do? Considering selling it or taking it to auction but I really like the vehicle. Anybody know what it would be and how much it would cost?
