I have a 1997 Dodge Caravan with 207k miles on it . It has developed a misfiring problem - It runs good most of the time but once in a while it will start sputtering till it almost dies- then clears up & is fine again

first, tune it up and pray that fixes it. If not have a pro like me scan it and test fuel pump pressure to see the problem area. realize those often become endless money pits at that age and mileage
