Inspect the MAP sensor vacuum hose for cracks. If cracked, the MAP sensor voltage input to the ECM may increase, causing any of the above conditions to occur. If a cracked MAP sensor vacuum hose is found, inspect the MAP sensor to make sure that there is no sign of flashing where the MAP sensor vacuum hose attaches. If present, trim the flashing and replace the MAP sensor vacuum hose. If there is no flashing, just replace the MAP sensor vacuum hose.
