99.9% of “mechanics” are not diagnosticians…first mistake !!…car dying could be a a fuel delivery issue or even a crank sensor…the 2101 is the PCM is not seeing the correct values between the commanded and actual throttle position…don’t know how your tech figured this out but you should find yourself a diagnostic or auto electric shop and take it there…can’t diagnose this over the internet unfortunately without a scan tool and a scope.
