Anyone else have this problem? My car has 160k miles on it and i figure it probably has tons of carbon build up because of oil burning. The timing is set and it has new plugs. I have also ran two cans of seafoam through it to clean out the carbon but it still preignites. The only way i can somewhat get rid of it is to retard the timing. Anyone else have this problem and what have you done about it>?

Get a timing gun and retard the timing a few degrees. Should be at 8
