I have a 2004 Dodge Grand Caravan 3.8 150k just did a much needed tune up on it. It has had problem off and on 4 a wile. On a cold take off car will hitch like your on gas off gas repeatedly. Has do it twice in the last 2 days now after the tune up. Not all the time will jerk on lite acc from a stop with no power. Then will also bang into 3rd gear for no reason wile driving. Check engine has been on do to a down stream 02 code.

Another problem I have is air bag light will come on after it rains. Go out once its dry. But the last time it has come on and stayed on.
