Update, still trouble shooting this thing. Since last post.
1. Checked and changed Injector with newly rebuilt one, put it on the LH side first no change, swapped to RH side no change.
2. Replaced the speed sensors with new ones, no help
3. Replaced throttle position sensor from 500 mile Turbo, no help.
4. Changed the rectifier with new, no help.
5. Put in new OEM plugs with new wires, no help.
6. Swapped coils with different set OEM, also tried some Dyna coils, no help.
7. Tested the PING sensor per Page 20-4 and 20-5 in the manual, works as described. No Help.
8. Tested the temp sensor and is in spec.
One thing that is strange, it will surge and sputter not moving, but when I put my hand over the intake it will recover and then rev up again. Any ideas?
