i notice lately my 00 se is not running as fast as it normally does..i have no CEL or anything....i'm thinking of changing out the spark plugs soon even thought my car only has 49k...someone suggest it might be my ignition coils or maf....what else do u guys think it could be? i don't think it could be the maf because i can rev past 3k rpm..the only performance mod i have is a cattman y-pipe...

 

prob your ignition coils, im going through the same prob right now
