i have a 91 accord and it idles real rough, it hesitates at the beginneing of acceleration and my sports light blinks. i told that it could be the egr valve. anyone know wht it could be. also when i break, whether at low speed or high speed, my steering wheel shakes a little and my car pulls to the right. i am not sure if it is just my front end but there is a clunking noise when i turn and a clicking noise when i turn sharp. any help will be great.
