2016 IA rough start, no acceleration

So I got gas the other day after driving on empty for about 5 miles. After pulling out of the gas station I tried to accelerate quickly, but the car lost power and jerked forward. This has been happening every time I try to accelerate quickly, or go up hills- misfiring sounds from the engine and loss of acceleration. If you drive really lightly on the pedal and accelerate slowly the car drives more or less OK.

When I start the car in the morning or after it hasn’t been started in a while, it misfires and shakes the whole car for a couple seconds before finally starting.

Scan of the car yields code p0193. I’m not a “car guy” but my mechanic is having trouble diagnosing the problem. Wondering if anyone has had this issue. Any help would be appreciated. Thanks!
