We just got an 04 Grand Caravan w/ 116K on it this past month. The CEL came on about 100 miles after we bought it. It reads code P031 Cylinder 1 Misfire. Replaced plugs, wires and coil pack and had the PCM flashed. I also had compression checked and that was fine. Light still is on. Essentially, it runs really rough when idling. If I rev the engine slightly the miss goes away. When driving at highway speeds you can not feel any type of miss. Also, Im not sure if this is related but everytime I fill the gas tank up and drive maybe 500 feet the van will***** harshly then drive fine. It has even stahled a few times directly after filling tank and idling. We haven't gotten the title back from the state for this van, but we are seriously considering selling it already. I want to fix it but noone can tell us what is wrong! Any suggestions would be GREATLY appreciated! These are just the first two of it's quirks that we need to get fixed. Thank you!
have the same problem?
