> OK.
> As Chuck said there are several things that may be at issue.
> First, the injectors themselves only flow what the metering unit delivers

> Is the air flow plate centered in the cone when the plate if fully down so
> it doesn't drag on the walls of the cone?
> This would obviously keep the plate from dropping all the way down and
> shutting off fuel flow.
> Does the air flow plate drop to the bottom of the cone?
> There is a stop underneath it that may be midadjusted and holding it up.
> With the fuel pump running, if you try to lift the air flow plate, does it
> lift freely for a small distance then hit resistance?
> This would indicate the plunger is sticking. Not sure the cure for this

> Last, if the air flow plate is fully at the bottom of the cone and the

>> As I figured, the CSV is good to go. No gas coming out.
>>
>> The injectors, on the other hand, ARGHHHHHHH! My mom even said, "Oh,

>> they shouldn't be spraying.
>>
>> So, guess this answers the question of why I have fuel in my oil. Now,
