ok... when i'm taking off in first gear, my car seems really weak, then all of a sudden it feels like the power is kicking in. what could it be? i have a stereo system in my car and i bump it, could that be draining my battery? could it be the alternator? or could it be my clutch?

 

do you have vtec? i dont think that the stereo would make any difference. but i do know that power steering and AC do sap a little power.

 

yea i have a '00 si. the power seems low from 1000-3000rpm... then after that it seems to kick it... it doesnt do this all the time... just here and there

 

vvvvvvvvvvvvtec it feels good

 

what are you shifting at? that happens to me if i shift at low rpms.

 

It's called having a B16A. They're torqueless wonders. No power until midrange, and then vtec kicks at 5500.

 

Possible timing issue.

 

but how come it doesnt feel like that all the time? most of the time, it feels like all the powers there... most of the time it happens in 1st and 2nd gear... im usually shifting around 3 or 4 rpms...

 

same issue, probably small exhaust leak or something, or fuel.

 

ok... thanks you guys... i hope thats the problem

 

post pics of you si ftw!!
