I have a 2009 500 EFI that idles great but sputters when I drive it. I thought it was the fuel filter, but I changed that and it is still the same. I have also changed air filter and looked for obvious loose connections and checked fuel lines for kinks or leaks. It doesn't do it all the time, but it cuts out bad when it does. It'll run great for miles and then all the sudden it will start sputtering. I use high octane gas (93). I am so frustrated, it has always ran great until last week... My next guess is the reverse limiter switch, but I am just shooting in the dark... Any help would be appreciated!!!!:aargh4:
