yea i was thinking the same thing about the spare, luckly i have a buddy with a skyline about 20 mins from me with alot of spare parts. he is going to let me use his spare to see if it still messes up. I was thinking maybe my cas is 180 off, the car will run both ways just on the number 6 cyl first instead of the number 1 cyl. I was making changes this morning while driving into work and when i would retard timing things got better when i advanced them it stayed the same or got worse. hmmmm bad thing is i dont have much time to work on it cuz work has a ton of trucks that have to go out so i am working all the time and not getting quality time with the car.
