The valves are adjusteable with an allen wrench and a 14MM wrench IIRC. All you need is a feeler guage available from any auto parts store to adjust em.
I am glad it is running good too. Don't know why fuel milage suck on new injectors, all I can to is get about 520 miles on a tank of fuel...about 20 mpg. I am used to 23 mpg but it was mighty windy out today.
