Found a problem in my ignition system.
My MSD coils that are over 12 years old, have some rotted connections. I attribute this to some water/moisture getting in there over the years.
So a new set of coils and a new set of spark plug wires later and the car seems to be running stronger.
I also installed a MSD Tach adapter to feed a clean RPM signal to my Quick 6 trans controller. So far no OSS Error codes anymore while doing a burnout.
True test will be next time I goto the track.
Had my new tuner riding shotgun watching the laptop and doing datalogs.
She had no fear. Better than some grown men that have sat in that passenger seat. LOL
