Hi everyone, I own a Toyota Spacia GXi 1994 model. I bought the car second hand of a friend and had no problems so far. Since a couple of month the car engine started back or fail firing in low refs (under 2500 rpm). I was looking for a repair manual online but couldn't find any. Another friend told me it's fuel injected so I could not be the spark plugs, because it doesn't have any? I have to say I don't know much about cars but would like to figure it out myself if it's just a dirty/faulty connection around the engine? I would really appreciate if someone has an idea what could cause this problem? Thank you very much! Kind regards, Martin
