A couple of years ago we had the issue with the OEM intake gasket cracking and letting air in causing the car to idle really bad and throw a CEL.
I ended up replacing the gasket but the one that replaced it wasn't the orange or red gasket, it was another black (maybe old stock??). Anyways it fixed the problem right up and everything was great again.
Fast forward to the last few months and I have noticed the engine seems to idle at a lower than normal RPM and also shake a bit more noticeably. I also am concerned because when I blip the throttle I can hear a sucking noise from the engine bay like its sucking air NOT from the intake area.
I haven't had a chance to have someone blip while I have been under the hood but could this be the same seal coming back to haunt me again or should that seal (as bad as they are) at least last a few years before going bad again?
