With mine its usually intermittent misfire in one or more cylinders. Do you have a code reader? Have you changed the plugs recently? Supposed to be changed every 2 years apparently.
Did you get it fixed, and if so what did you do? My wifes copen has a misfire and will be checking plugs etc this week.
Yes, did get it fixed. The guy I bought it from brought his diagnostic kit round, which showed it was to do with fuel delivery to the engine - tube had become wedged and twisted round another, so it was a simple sort out. He also told me to make sure I was using super unleaded.
You guys still have regular unleaded? We don't since 2009 or so... We have Super E10, Super E5, Super Plus. Runs great with Super E5, E10 is not permitted by Daihatsu
