I will try my best to help you and in order to do that, I need you to describe the issue in as much detail because I only know as much about your vehicle as you have told me in your post, so my answer will be based on what you have posted. Please include all the small details that may seem insignificant such as warning light or noises.

My goal is your satisfaction and I ask that you not accept unless you are satisfied, but if you are satisfied, please accept so I can receive credit for my work and time. Positive Feedback is greatly appreciated and bonuses are always welcomed.

The way I check for a vacuum leak is with a can of carb cleaner. I spray it around the intake and all the vacuum sources. IF the engine stumbles, you know you have a leak there.

What issue are you having and what codes.

Expert:  GM Tech (Cam) replied 7 years ago.
Yes, you need to hear how the engine runs to see if there is a leak when the spray hits it.
