What should I do when my dodge caravan is surging constantly especially when you slow down or stalk in traffic. I have taken it to two different mechanics and they could not tell the cause. please help
I had this happen to my 05 Town and Country. I don’t remember if it threw a code, but I don’t think it did. My wife drove it and said it almost threw her into the highway as she approached a stop sign. It wasn’t that bad, but it surged tremendously when I test drove it. I removed the throttle body, took all sensors off the throttle body, used throttle body cleaner and rag and thoroughly cleaned throttle body. Worked like a charm.
I would look at replacing the IAC (Idle air Control.) valve.
