I am also having the same problem with our 99 grand caravan 3.8 liter. It is getting worse. We just had a tune up about 15000 miles ago and originally thought we might have water in the gas, but after putting gas treatment for 3 tanks full it just keeps getting worse. We have changed the air filter and are getting ready to change the fuel filter. The O2 sensor was going to be my next move if the fuel filter doesn't work. I am trying to go from the cheapest up. I am afraid to take it to the dealer because they lie and rob you blind. We bought this vehicle with 69,000 miles and now have 110,000 miles. In 40,000 miles we have done over 4,000 dollars worth of stuff. I dont' believe I will ever buy another dodge, they are not built for longevity. Anyways. Anyone have any suggestions for this ping or backfire problem?
