    Rough Idle Problem!! Need Help!!

    Im not sure what the problem is maybe i need a new fuel filter but would that cause a rough idle to were my car almost stalls? I also notice that my vacuum gauge likes to go a little crazy. Its even worse with the A/C on. If anyone has any ideas please let me know. Thank you in advance

    You probably have a loose hose or a leak somewhere between your maf and throttle body.

    I got $10 that says your bov is leaking

    Check air filter box is closed properly, sometimes tabs on the bottom don't go in properly.
