Answers :

It sounds like you have a fuel issue. you should check for proper fuel pressure. its should be 48 PSI.
\015\012if its not, it could be a clogged fuel filter, a malfunctioning fuel pressure regulator, clogged fuel pump strainer, or even a bent, kinked fuel line.
\015\012if the fuel pressure is correct, its most likely a faulty fuel injector.
\015\012by the way, you car doesn't have a mass airflow sensor, it has a MAP sensor
