my car was stalling and I check my mass airflow sensor and cleaned it out and put it back on and my check engine light went off for one day. I also disconnected and reconnected my battery. car continued to stall and cut out in the middle of driving it. today in traffic I stepped on the accelerator and it winded up and then I lost a lot of power. as I pulled off the main street on to a side street I noticed that it was making a clicking sound and made more of a clicking sound when I stepped on the accelerator. Can you please tell me what could have caused this or what it may be?
