I've noticed my car is really losing power..I'm thinking that fuel filter is part of the problem..has anyone replaced their fuel filter yet..and what improvements if any did you notice... btw i changed the spark plugs and air filter..car still lags..

Well could be a number of thing how many miles do you have on the car . do you drive fast or slow. could be carbon build up on the valves or clogged injectors . When you replaced the spark plugs did they looked fouled . You could first try some of that in tank FI cleaner but sometimes that doesnt work that great . You could go to a shop and have them do a FI cleaner it works really well but you still dont know if thats your problem . Have you checked your fuel filter does it looked plugeed up or anything .

get a fuel injector cleaner. run out your tank and fill it up with high octane.

There is a diy around of replacing the fuel filter......it's not hard, but no easy either. It is in your gas tank and you have to pull the fuel pump out.
