i have a 2003 civic. i have done a cat back excaust. air intake, header. everyonce in awhile theres a slight hesitation. a friend has a civic and his does that also. someone told me when you do the work on the car you sometimes have to replace the om sensore i think its called. has anyone ever had this problem? a guy at a car parts store told me his does that he thinks its a honda thing

 

i have the 2003 civic myself and i have done exactly the same stuff!the problem you refer is because the sensor checks the rate of your engine smoke u know and because of your mods it is more than the original presets.it doesnt affect your car at all but you can solve this with a new sensor.i left it like that and i dont really care.in fact even at the honda dealership they can fix this(i trust them more than all the other mechanics who think they can make out 200hp with whatever parts they like!)

 

OM sensor? What is that?

 

OM=O2=oxygen sensor?

 

Did you reset your ECU after installing the mods?

 

yeah i think even if you recet it will show the same problem after some time has passed...anyway here we call it a measure sensor for the "λ" which is ratio oxygen/smoke or something like that look i am no specialist!

 

okay..............

 

yea thanks for your help. i guess when ever i have a few dollars ill replace the sensor. i hear your supose to replace then every 2 years anyway?

 

at the honda dealership did they say how they could fix the problem?

 

good damn it no they didnt they just told my how simple it was-i didnt even ask them to fix it they just did...its a pity though....if i learn ill post it
