Hi everyone,

I just finished intake manifold gasket and fired my 95 blazer up and took her for a ride. The check engine light came on, code p0304 about 1 hour into test riding. My GM tech 1 indicated misfire on cylinder 4 and I checked the basics and reset the code. Motor seems fine for now, but I found a vacuum hose that was not attached to anything. I downloaded a similiar picture of what mine looks like. If you take note of the ball, there is a "T". Where does the vaccum hose to the left (inserted in to the "T") attach back to?

Thanks bizzs

 

Not sure which 'T' you are talking about exactly. But it comes from the back of the intake manifold(passengers side) and feeds into the Ckeck valve(black/white) on the black side. From there it goes up into the reservuior ball and then reduces down to the second 'T'. This 'T' splits between the HVAC controls and the 4WD vacuum switch on the transfer case.

 

Thank you sir, you were correct. I didn't see the port because it was covered with the other broken vacuum line piece.

Merry Xmas
