| I have checked my spark plugs and they are the color indicating lean fuel mixture, in addition I have a surging problem that on another post they attribute to lean mixture also. How do I get more fuel to the engine? I have a 79 california bus. |

If your fuel pressure checks out as correct with the gauge, inspect the aux air regulator and look for vacuum leaks.
How new is the O2 sensor? |

| I have sealed some small dryrot in the s pipe and the vacuum line going to the air box has been replaced and is new. I dont think the o2 sensor is but 3000 miles old. and my fuel pressre is at about 38 psi and the fuel pressure regualtor hold the pressure long after the vehicle is shut off. |
