When i autoxed my 98, I had the tapping problem. The solution was to drive the car four 4 minutes at 4000 rpms in 1st or 2nd before the run. This was mentioned to me by a lady in a Supra. It worked.
I also drove the car at the same rpms after the run for the same amount of time. It never tapped after that. I plan to add half a quart every time I take it out for an autox weekend.
BTW, the lady whooped my ass. Damned 350hp Supra things.
