Thanks to Alex & Kevin for cleaning the carbon off the valves.
They did a thorough job taking every bit of carbon deposit out of the valves. I was able to view the valves before and after. I have approx 56,000 miles and after the walnut blasting, the car runs much smoother and I don't get that once and awhile thump when idling. The walnut blasting took approx 1.5 hours only. Since I was there, I also had Alex code the basics to my vehicle.
To top it off, I95 was clear and wide open going there and back!!
Again, thanks Alex and Kevin!
PS: You guys need to start another group buy....WATER PUMP!!
