actually not too long ago. However I changed the fuel filter, spark plugs, air filter and added an injector cleaner sat july 29 2007. After about 5 min of driving it was a very noticable amount of power increase. The fuel filter had dirty brown fuel come out when I dumped it in a clean jar. Possibly I got it?
