yeah, i should give this a try, it happens mostly mornings so I should hook it up and then start the car lets see. only problem is finding a tee that fits there.

Also I forgot to add, when I started the engine this morning, I heard the Pump running, it was going to give me that ASR light again, pump ran for 10 seconds and stopped. within 10 seconds It starrted running again, and I decided to higher the RPM and kept it around 2000rpm for like 15 seconds. Then pump stopped and didnt run again brake pedal became a little softer and ASR light didnt show up, so this is really directing me to a vacuum problem, what do you all think?
