Re: Very severe jerking accelerating mid-range
Sounds like an ignition coil problem. I had a similar issue. The misfire is worse under load and when the engine is hot.
Try disconnecting one fuel injector at a time until no difference is felt. This should tell you which coil is bad.
Any regular OBD 2 scanner will give you a misfire code if the check engine light is on.
