Cadillac Catera Check Engine Light and/or Erratic Engine Idle

(9 reports)

Engine vacuum leaks may develop from the various vacuum hoses causing the engine to idle incorrectly or the Check Engine Light to illuminate. Damaged vacuum lines should be replaced as necessary. Our technicians tell us that rubber vacuum hoses can be used to replace damaged plastic lines if necessary, as long as any connections are vacuum tight.

I noticed that the vacuum lines up by the Brake Booster was broken. I tried reconnecting it, with no luck of it being vacuum tight. Shortly after my CEL came on, and is still on. I am currently working to fix the issue. -
I have the same problem. No solution. Looking for one like you :) -
