The CEL came on a few weeks ago and then would go off and come back on again. I ran the diagnostic scanner and it came back with a lean code on the drivers side. I checked for air leaks and the vacuum hose circled in red is the culprit. It made an audible hissing noise and if i press on it I can get it to stop leaking. Does this entire hose need to be replaced or can i just cut off some hose and put the connector back on? I tried pulling on the connector but it was not going to come off easy. I suppose I could run a razor blade down the side and cut off some hose and reconnect it. Any help or tips are appreciated!
