I am going to replace my Mass Air Flow Sensor. I am kind of confused. I am looking online at Partsamerica and they have a Map-Baro Sensor which looks to be just the sensor part and a Mass Air Flow Sensor that contains from the picture a sensor and the air horn assembly. Am I right? Are the parts I identified so and do I need to replace the whole thing instead of just replacing the sensor itself.
Of course any change is going to be followed by resetting the computer. I cleaned my sensor last year and it made a big difference but now the symptoms are back and I knew I was just buying time when I cleaned it last time.
I had a hard time starting my car a few weeks ago and turns out my fuel pump was gone. It is OEM and had well over 100k miles on it. I got that replaced and the car has run fine. Before the fuel pump went out I started to notice some performance issues again which were exactly what happened last year and cleaning the MAF Sensor resolved the issue as per this newsgroup! The MAP is OEM and now I know I need to replace it.
I was wondering if a faulty MAF Sensor can cause hard starting where the engine just turns and does not start and after some amount of time the vehicle will start. I am sure my MAF needs replacing and I guess I will find out the answer to some of these questions soon but before I do so I look forward to hearing what you guys have to say.
Thanks,
