i have a 99 prelude which the car bogs alot...i was wondering if you have air bubbles in your clutch lines or clutch would that cause the car to bog???

 

no, but it will cause the clutch to be very soft - if not sticking to the floor.

What mods do you have done?
Whats the very last thing you've done to your car before the problem started?

 

No, that will NOT cause your car to bog.

What led up to the bogging?

 

well i swapped in a 99 h22a4 with 60ks miles on it and i put in a stage 1 clutch with a 12lb flywheel...i also bought new headers for it..also the car has intake and exhaust system on it before....and hrmm i took out the power steering..

 

i swap the motor by myself with help of friends

 

could be you have your sensors hooked up backwards, or you have a vaccum leak on the manifold. does it bog all the way through the rpm band or does it rev up good after a certain point?
