I noticed yesterday, after driving home and doing some good boosting, that when i come to a stop, i'm losing vacuum (-17mm/hg @ idle) and the car seems to be hesitating and idling a little higher. The vacuum hoses seem alright and in place. Also, the car bogs a little. If i shut the car down and restart, everything is back to normal after my next boosting session. what's wrong?

 

no solutions? come on help me out!
