V6 engines may experience surging while driving. The condition is more noticeable between 40 and 50 MPH while accelerating up a hill/slight incline. Replacing the powertrain control module (PCM) and updating the transmission control module (TCM) software may be required.Google+

Chrysler Town & Country Surging While Driving Between 40 and 50 MPH
Chrysler Town & Country Problem
Average Mileage: 103,438 mi (14,600 mi - 230,000 mi)
Same surge issue since purchased with 50000 miles, though more pronounced now. At 65 mph the stutter is essentilly nonexistent. Below 60 mph, I can sense an occasional stutter. Around 35 mph (common street speeds) the engine will sometimes surge with noticeable tach fluctuations. Pressing further on the gass pedal will make the surging go away. The throttle position sensor change did not help. Would like to get this fixed if possible.

Replacing the EGR fixed the surging issue I have had for a couple of years. Pull the vac hose and plug/cap. Take the van for a test drive. If the surging goes away, the EGR needs replaced. Apparently crud gets into the EGR valve and prevents proper operation

At light acceleration, there is some feeling of engine missing/trans surging. Dealer said it was not detected but installed updated software. Still happens especially when engine is cold.

I have a surge when coasting around 40-45 mph. This has gotten worse lately and is starting to drive me crazy. I haven't diagnosed it yet but had a similar vehicle in the shop the other day with this problem and it turned out to be an EGR valve. Unable to verify that repair yet with my van but soon.

At 90,000 miles, my 2002 T&C EX van developed a speed fluctuation problem. For several months, I experienced intermittent engine surging; particularly at 50-60 mph. Engine rpm would suddenly fluctuate causing the car to slightly jerk. I replaced plugs, wires, gas filter, cleaned injectors, cleaned throttle plate, other to try to fix the intermittent speed fluctuation problem. No luck! At this point, I was convinced the problem was with my automatic transmission and that I was about to encounter a VERY EXPENSIVE repair cost. Just before I took the van to a local transmission shop, I did some extensive research on the Internet regarding my van's engine surge problem. After spending several hours searching the Internet and not finding any new repair solutions, I stumbled across someone's repair suggestion which I had not considered. The T &C van utilizes a throttle plate sensor (TPS) which provides throttle plate position feedback to the van's PCM. This sensor sometimes fails. I decided to spend a whopping $20.00 for a replacement Dorman TPS as my very last attempt to find and fix my van's speed problem before I made the trip to my local transmission shop. When I removed the sensor (no easy task!), I found the sensor partially filled with gas/oil residue. I replaced the sensor and my engine speed fluctuation problem disappeared. FINALLY!
I now have 130k miles on van and I have not had any speed fluctuations of any kind since replacing the inexpensive TPS. I love the Internet!

Exact same problem!

Shakey, surging, feels like transmission is not engaging correctly.

when idleing or driving more than 45 miles per hour, the 2001 van shakes

Same as others describe. Seems to surge between 50 and 60. Not really noticeable
above or below those speeds, at least not yet.
