clogged cats?
bad petrol?
faulty plugs/coilpacks?
dirty AMF?
faulty o2 sensor(s)?
other engine issues.
evap purge valve?

what troubleshooting steps have you done to try and find the problem? did you pull any codes at the obd port?

when did this start? have you had the car long? what's the history and maintenance of the car?
