at first the my S felt real strong but now is seems to not have as much pick up for some reason. it seems to lack power? anybody have ANY ideas, ANY at all?

 

hot weather? heat soak.

regular maintenance? air filter, oil, plugs, etc. might want to reset the ECU just to see if it's learned anything you don't like.

or maybe you're just used to the car now.

any mods since then? could be robbing power. wheels and tires?

there are lots of possible culprits. maybe if you could describe a bit more precisely what's missing.

 

well I do have wheels and tires now. 18's. I have CAI and do reg oil change but have not changed plugs in a while could that be it maybe and if so what are some good plugs money not issue.

 

18s can def slow you down. Heat im sure plays a role as well. How old is your CAI, maybe try cleaning the filter

 

brand new CAI, it is hot in TEXAS

 

18s will have a pretty noticeable impact on performance with this car, especially if they aren't SUPER LIGHT. what size tires are you running?

you may have lost torque at various points in the powerband with the CAI depending on the particular type. plugs are probably not a problem if the car is fairly new and you haven't done anything to cause it to run really rich.

did you notice this sluggishness gradually? suddenly?

a trip to the dyno would be the sure way to verify how much power you are or aren't putting down.

 

it is sluggish to a point then gradually it will gain acceleration but slowly it seems. its 4-IG CAI.

P.S. thanx for caring!

 

It's not your intake I have the same one and have never felt a loss. reset the ECU and see what happens.

 

the other day it was very hot and i was driving my car, i engaged vtec and the car didnt feel as fast as usual. i thought i was very low on oil or something else was wrong. i went home, checked out the oil level and it was perfect. i later went out with my girlfriend that night and as i was driving to her house, i engaged vtec, and this time my head was planted into the headrest. the air temperature was very cool that night.

anyways my point is, ambient temperature/humidity makes a big difference on our motors, especially since its only a 2.0 liter motor. i can't wait till fall/winter, our cars perform their best in those seasons.

 

OK finally guys I reset the ecu and it is running back to new again I sure wish I would have known about that before. thanx for all the input guys it helped alot.
