What exactly is P0401
I got this code today... I researched but theres no exact answer!
Is this code critical? It says insuffucient flow or something.... so i just cleared it! i noticed that before the check engine light appeared my car sounded like gona stall and i saw the drop of RPM too.
HOW CAN I FIX IT? or Is this just a random code that we get sometimes????....

you have a vacum line disconnected from the bottom/backside of your throttle body. Common problem. You need to feel around a bunch to find it, but that is what causes this most of the time.
