So since I got my 7G i had this problem , when I drive normally I its all good but when I floor it cars chokes/shakes rmp is between 2 or 3 and it doesn't accelerate. If I i press gas gradually it goes up to red line but if I floor it i chokes and control light goes up its says its misfire , 1)Cables 2)Spark plugs 3)Fuel Filter 4)Injectors 1 year passed and I did all tune up parts plus fuel filter and checked injectors and still the car chokes when I floor it. Today i was talking to my friend who is a mechanic he said it looks like its Mass flow sensor or Mass flow adapter. He also told me to change air filter. I'm thinking about putting Short Ram Intake , I would also change that flow sensor and flow adapter but are those parts expensive? and also do you think it might be it? and third what are those things really doing? Maybe little lesson would be nice ;) Thanks!
