Hey Guys, 

My 3.8 Gen3 is running really rough and jerky accelerating below 2.2-2.3K RPMS, after that it smoothens out. Any Ideas what could be wrong?

 

Cheers, 

Jas

Try disconnecting the air flow meter and drive a bit and see what happens. If the problem goes away, you need a new air flow meter. Don’t drive long term with the airflow meter disconnected, it will cause other problems down the line.

Other causes can be bad spark plugs or coils, amongst others. Weak spark can cause hesitation under load.

Doing a diagnostic scan is the way to go but I’d try disconnecting the airflow meter first. Pretty common fault.
