so ive been wanting to do the timing advance deal for the ga16de and i never really ran the high gas cause i didnt need to but i filled up on 92 and went home to do the timing, i had someone tell me step by step and it was already advance to 15. 111121 <-----the 1's are the marks on the crank pulley and the 2 is where my pointer is pointing whil in timing mode that is if your looking from the front of the car. ive never heard a ping or anything before. WTF? plus what ngk plugs should i be using , i got the v power ones but i dont kno if they are the best. let me know what you think about this deal.
