    M42 idling Problem

    hello youtube! hey, so heres a video of my car idling right when i start the car. it will idle for a couple seconds before it starts to die on me. this only happens when i start the car. once ive driven around the block a couple times the idling is fine and wont die on me. can someone please let me know what the problem can possibly be? thankyou. p.s. I have a new 02 sensor and ICV

    Vacuum leak somewhere is likely.

      definitely a vacuum leak, most common is the intake boot they crack all the time, or one of your vacuum hoses has a crack
