Hi. My 1999 1.6 vw golf is loosing power and is very jerky. I have a feling it is to do with the air intake. How do i fix this?

If you sure about problem on intake. Take your intake booth maf and air filter complete box out of the vehicle. inspect and clean your intake booth check if any posible air leak on it, check your maf sensor (use only maf sensor cleaner another cleaners may damage your sensor) if no any leak go to air filter box make sure air filter is in good and clean , on bottom piece of filter box there is another filter screen from the air inlet from out side make sure it is clean (get clug a lot from out side dirts ) if you did not find any cracks thats causes leak any air intake completly clean and still have problem you may go another step . good luck
