I have a 79 camaro. Had the engine rebuilt a few months ago and it ran like a dream. Now, after returning from muffler shop, it acts like a vacuum hose has come off. I can't seem to locate a diagram to see if all the hoses are attached to the carb like they should be.
Help...

 

hay welcome to the forum. moved your thread to the 2nd gen section, should get a response here. when you get time read the rules, thanks. enjoy the site.

 

There should be a diagram under the hood.

 

Try this link. They list a bunch:

The muffler shop, eh? They may have knocked off or broken a vacuum hose while working under the car.
The vaccum modulator on the trans is one thing that comes to mind.

 

Thanks to all for your advise. I was able to locate a couple of vacuum hoses that were not connected.
Also...Thanks for the info on the vacuum modular on the transmission.
Anyone know of a good website to purchase interior trim?
