The more I look at my 88 firebird the more issues I find with the vac system. The engine was rebuilt but not rewired flawlessly. Can someone who has this car or a similar one send pictures of the vac system. Specifically the EGR system and the lines from the purge cylinder but really anything is good. Thanks so much.
It is a 5.7 TPI. I have looked at those diagrams as well as in the manual. The only one that has the purge set up the way I have it is shown below.
I found this emission routing diagram. The purge control valve has two hoses. One to the throttle body and the other appears to tee into the line that goes from the underside of the throttle body to the egr solenoid.
Am I correct about this? Are those all vacuum lines?
