how do you know if your intake manifold is bad or leaking? please help. thanks

 

there will be a big crack in it and your engine will run like crap

 

good call.

 

were would the big crack be?

 

when i replaced my fuel injectors i had a leak in the intake manifold gasket that was small, but i notice the throttle response was horrible.

this is what i did to locate it. i bought a few cans of carb cleaner. turn the car on. with the plastic tube on the spray nozzle, i sprayed along anywhere i suspected a leak. the car will start to idle different once the carb cleaner is spayed over the leak. once you pinpoint where the leak is coming from, replace a gasket if applicable or try to fix the manifold. this worked for me so it should work for you. good luck
