I did what you said to me ray. The way i clean the injectors is:
1. check the coil and leaks
2. clean the excess of carbon and oil with a needle (in the fuze)
3. clean with carbon clean spray
4. I put 12 volts in the coil and inject air compressed (120 lbs)
5. again i put 12 volts in the coil ad inject carbon clean spray
6. clean the fuze with a mototool (brush)
7. again i clean all the injector with carbon clean spray
thats all
