I have a 2004 Volvo S60 2.5T with about 101k miles on it. Recently I got a message on the display that said reduced engine performance light and the car started surging at idle and eventually stalled on me when I came up at a stop light. I restarted the engine a few times and it ran normal until the a couple of days later. This time the same message came on but the car would not let me RPM higher than 1k. Needless to say I was going about 15-20mph on a busy street. I did some googling and a lot of the people with the same issues said disconnecting the MAF would temporarily fix the problem but would need a new MAF soon. The part is on order along with a new air filter but today as I was arriving to work the issue started again and would not let me accelerate. I'm now wondering if the MAF is the real issue or there might be something else. Any advice is greatly appreciated, as it is the only car I have and I am on a tight budget. I was able to take it to get the code read and this is what they found P0102, Replaced mass airflow sensor, P0101,P2177 Replaced mass airflow sensor, P2111 Replaced Throttle Body, throttle body gasket. Thanks!
