I got a 2000 civic , anyways, by modifying the position of how the distributor goes on to the engine. It either make the gas more sensitive or less. Explain to me how this work. And if modying the position is bad for your engine. I have it all the way forward right now, which make the gas seem very powerful. can some one explain this to me?

 

You're advancing the timeing and retarding the timing.

 

is this bad for the engine?

 

it can be. If you advance it too much (like you're doing) you're causing the spark to happen earlier, so if you run shitty gas it can cause detonation and kill your motor. But i doubt you're adjusting your timing the correct way. If you're just loosening the bolts and turning it, that is not the correct way. You need to jump the service connector to put the car into base timing mode, and set it with a light. Best way is to advance the timing about 3 degrees from stock using a timing light (with the car in base timing mode), and then run good gas. Otherwise, save your time, set the timing to stock and drive it. You won't really gain much power, but like you said it will feel more responsive.
