This is an EVAP system trouble code. Small leak detected. The EVAP system pulls gasoline vapors from the gas tank into the engine to be burned instead of being released into the atmosphere. Unfortunately, unless its the gas cap, you're going to have to get a smoke test done to find the leak. A small EVAP leak may not be able to be seen with the naked eye. HTH. -Jim


I wouldn't think an evap leak would make it run crappy , when did the trouble start ? was anything else done to the car before this ? you can check EGR , loose or cracked hoses ,, clean AIC pocket , MAP , MAF sensors with correct cleaner and spray carb. cleaner down the throttle
