Hi guys, I bought my mazda 3 S 2.3 2004 almost a year ago, it has a mileage of 125K so Im looking for some maintenance tips and things you would recommend to check/replace on it.

I've notices it a little bit slower, the feel is like of a heavy or tired car. sometimes hesitating a bit at the start

I added a new Intake so the air filter is new. I've also cleaned the MAF sensor and also will be replacing the spark plugs with NGK ITR6F13 Laser Iridium next week. that will hopefully do some difference....

What else should I be looking for here????? we usually don't know what kind of maintenance the previous owner did to the car so, assuming they just did the normal oil/filter changes. what can else should I look at?


thanks every one!
