Maintenance/Repairs

My girlfriend noticed her 98 Chevy metro was not running well. We ran a diagnosis tool and it was giving 02 sensor codes. The car would start but wasnt running well and would stall after running for a while and hitting the gas would sometimes stall the car, and other times would rev the engine as expected. We replaced both 02 sensors and nothing changed. We started checking the intake the car would run just fine and pep back up if we sprayed carb cleaner into the intake. Leading us to believe it wasnt getting fuel and needed a new fuel pump. To big a job for me to do in the driveway so we took it to the shop. After doing some of their own testing they noticed I’d you sprayed the carb cleaner anywhere near the intake the engine would come back to life. They believed that the vacuum was leaking somewhere and that was the cause of the troubles. They replaced the intake gasket, and fuel injector gasket. No change. Any thoughts or ideas about what the problem could be would be greatly appreciated, thanks!
