Dose not seem to be missfiring, altho it dose have a hicup evernow and then but its not offten at all.

i spose that could be a lead

If i have to describe how the car drives i would say it feels like its a lasy engine and i have to work it to make it go, sort of like its resisting, dose not want to rev, so im thinking now a cat has been mentioned that it could be somthing to do with that, are these engines normaly like this?
or am i too used to the free reving golf?
