Hey Cindy! Looks like your car's gasoline system, specifically the fuel injectors or fuel pressure regulator, may be having problems.
Your engine may misfire, surge, and stall if your fuel injectors or fuel pressure regulator aren't operating properly. A check engine light and tachometer oscillations can also appear along with these symptoms.
It's still possible there's a fuel system issue even though the diagnostic test found no problems with the ignition system. To make sure everything's in order, I'd suggest having a qualified mechanic run a fuel system pressure test.
Low fuel pressure could be a sign of a broken fuel pump or clogged fuel filters. It may be necessary to clean or replace the fuel injectors if they're not functioning accordingly.
In addition, if the check engine light only illuminates occasionally, your car's computer may have a fault code that might help identify the problem. You can have your trusted mechanic use a code reader to access these codes and perform a more precise diagnosis.
