i have a 99 civic ex and i have been noticing a lag in my throttle response and the overall performance of the car i think that it is my fuel filter but after searching i was unable to find much information about it; so my question is where is the filter located and how do i replace it?

 

it's in your engine bay. its right to the right of the battery and has a fuel line going to your motor.

 

black cylinder on the bulkhead with a hose coming from the top, try putting some fuel line cleaner through first could be a blocked or dirty injector

 

thanks for the help i found the filter, but i have heard mixed reports on fuel/injector cleaners are they safe to use on a engine that has 112k miles on it? and what brands would you suggest or are they all the same?

 

absolutely no risk in using a fuel injector cleaner. just get any legitimate brand; eg STP, DuPont, NOS, Lucas...

 

thanks for the help guy i jus started to run some injector cleaner and it has made a huge difference.

 

i run BG fuel and motor additives, IMO its the best **** ive ever used, wont go back to anything else....
