Chevrolet Cavalier Rough Running Engine Due to Vacuum Leak

(5 reports)

The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.

Just replaced my oil pressure sensor and the day after I started having problems where my engine would studder sometimes while idling and sometiems shut off while slowing down or turning. I think one of my vacuum tubes is cracked so this would be the cause I'm assuming -
same as described except i lose my brakes when the car is running badly my break pedal is so hard to push i almost gotta stand on it to stop. and it dies when i stop at lights or slow way down to turn or wait on traffic,. also transmission shifts very very hard like. .. -
used carb cleaner to spray onto the vacuum hoses. Replaced affected hose. -
