car stutters when pressing gas · hesitation on acceleration
The car jerks, stutters or hesitates when you press the accelerator, instead of smoothly picking up speed.
Check whether the check engine light is on and flashing - a flashing (not steady) check engine light during a misfire means you should stop driving as soon as safely possible.
Generally safe for a short trip if the check engine light is steady or off, but get it diagnosed soon - it will likely get worse.
Describe your situation more precisely (e.g. exactly when it gets worse, how long it lasts) and get an expanded, personalized breakdown.
