i checked for codes.
There is p1259-manufacturer controlled fuel and air metering. And. A emissions code. I had no troubles till I removed the vtec spool valve, I believe it called on the back of the head. And cleaned it with Carb cleaner and replaced the gasket/o ring. Has rubber square type seal with screen in bottom of seal. Only thing I have done latley to it. Has never done this before. What does that valve solenoid do? Thanks!!
