Hi i have had my check engine light on for a while now. just the other day my parking brakes light came on and my dad has changed the oxygen sensor. it seems to be picking up a lil better now. the problem now is just that cylinder 1 is misfiring. i read the code and it gave me a 8 which is top dead centor position or code 17 which is the vehicle speed sensor. i have tried looking for it and i cannot seem to find it. could you tell me what you think is wrong with this car. im tired of it flashin while driving.

the car is a 1997 honda accord vtec. 2.2l 4 cyl 2 door
