intake manifold

well ive been lucky enough to have had my intake manifold gaskets replaced on my 2000 grand am gt. i also had front/rear brake servicing and fuel filter replaced and blower resistor.

my car is now having "pinging sounds". i called the service guy and he said sounds like a possible "Vacuum leak". What the heck is this? I spent close to $2000 and am not going to spend anymore.

car runs smoothly, no other problems except the constant pinging while in idle and driving.

any help would be much appreciated.

Don't feel bad, so far my 98 Grand Prix GT has had the following problems: Drivers door power window motor, water pump, air conditioning evaporator, alternator, the dashboard information module (the mpg, miles left, oil life, etc. thingy), both rear rotors and calipers, and right now I am faced with an overheating problem and an airconditioner that don't work (compressor I think). Fortunately the first 4 problems were fixed either under the 3 year warranty or an extended one I purchased. The car has less than 50,000 miles on it. I love the look of the car but to me that's an awful lot of problems for an 8 yr old low mileage car. I'm afraid to take it on any extended trip for fear that I'll get stuck in the middle of nowhere with a problem, that's what happened when the alternator went. Unfortunately this has left a really bad taste in my mouth about Pontiac's.

Jeez...dealer replaced my intake gaskets and blower motor resistor all for $300 + Goodwill coverage from Pontiac on my '01 GA.

Vacuum leak could be a loose hose or fitting, a leaking gasket, maybe bad EGR valve. The leak lets unmeasured air into the combustion stream, causing lean running which results in pinging under load. There is a chance they left something loose during the gasket repair; they should offer to at least look at it as a courtesy I would think.
