Vacuum to the egr valve on my 89 chevy van with 3o5

I have a 89 chevy van with 305. the egr is not working properly. the vacuum out of the throttle body is good but there seem to be no vacuum coming out of the egr valve. is this because egr valve is stuck closed or is there another possible cause for no vacuum at the egr?
if the egr valve is stuck can i clean it by spraying or soaking it?

Where would I check for airfow and vacuum problems in a 1994 chevy Astor van.


Under throttle body. Take a can of carb cleaner(make sure you don't have plug wires breaking down) spray under throttle body if it changes the way the engine runs you found it. Egr and pcv are other less likely. Should be getting a lean code if you got a vacuum leak

Where is the fuel pressure regulator on my 89 G20 Chevy van?


Underneath the throttle body , it's serviced by removing the TBI Unit and flipping it over , your fuel pressure should be between 12-15 psi with a proper working regulator.

Check the vacuum line to the fuel pressure regulator and check to see if the fuel pressure regulator has gone bad. Give the throttle body a good cleaning and the injectors too. Do not use carb cleaner, it's to corrosive for the gaskets used in the throttle body. The other thing too that would cause this is a stuck or bad EGR valve, Try cleaning the EGR valve too since your cleaning the throttle body. Good luck and keep me posted.

Egr valve is bad on my 1989 chevy with 305


You block it off before the valve on the metal pipe that runs to the EGR valve. The problem is that when you go to get it smogged you have to replace the EGR or it will not pass smog
