Alright I ran the ECU code thing and nothing came up as bad (0505) I also just changed the fuel filter and got no difference in performance...If my plugs are bad will it Hurt Performance Alot ? Cause I am getting good gas milage and its running smooth but my performance sucks ?? Maybe I just need a Y-pipe too let more air out from the cold air

 

what do you mean your performance sucks? Its not like changing your fuel filter will suddenly increase your acceleration. All it did for me was get rid of my starting problem..

As for the spark plugs, how long ago did you change them out? You might wanna take them out and see what kind of condition they are in.
Good luck.

 

Well my real question that I ment to ask in my original post is "Will bad plugs hurt performance by alot (Enough to notice when changed over)"

thanks guys, cause I really dont know when they have been changed cause I bought the car last year and thats the last thing that might be hurting my performance Unless My Compression Sucks

 

take them out and check... if they are all blackened or look burned, its probably time to change them.. the interval is every 60k though, for the stock plugs, so it depends what mileage youre at.

go with ngk platinums if you are going to swap them out, they are the best for our cars.
