Cleaning May Correct Faulty Mass Air Flow Sensor on Toyota Corolla

The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.

Engine has low power, and does not accelerate. Hesitates at times. Engine light is on. Sometimes engine stops running when slowing down or stopping on intersections. Sometimes it would run but RPM is steady at 1,000 to 2,000 RPM's and at 10-20 miles per hour speed, until you restart the engine and it would run normal again for sometime. 1. Cleaned MAF sensor: did not fix the problem 2. How to make sure that MAF sensor is faulty and need to be replaced? 3. Any recommendation?

Looking for suggestions to resolve this problem. Cleaning MAF Sensor didn't fix it. How to make sure that MAF sensor is faulty and need a replacement?

The Check Engine light came on with MAS and Bank 1 too rich trouble codes being reported I cleaned the MAS with just canned air and the problem went away for three weeks before triggering the Check Engine light again. I am wondering if the OEM air filter that was installed about 3000 miles ago is defective and restricting the airflow so I just changed it out. I am also wondering if there may be some particles being released from the secondary charcoal air filter that may be collecting on the MAS wires that is causing a recurrance of the check engine light. I will be waiting to see if the light comes back on any time soon.

Lucia 2001 corolla. Does not accelerate rapid (excuse my English), but the worst problem is that the engine does not start when hot. In the morning starts ok, when I stop the engine after a trip, if I try to start it again before it gets cold, it does not start. Chech engine light is on. I disconnected the O2 sensor and nothing happened. I put a new fuel pump too. I measured all four injector's coils,.they are ok. Help! Please

Ongoing problem that manifested itself during -30 to -40 degree days in winter now comes on in summer as well. Codes p0102, p0113 and p0171 have been observed. Cleaning MAF worked for a little while with CRC cleaner but codes keep coming back. Considering replacing MAF since wiring appears to be fine.

I'm experiencing rough idle and sometimes sluggish acceleration. I have tried to clean the throttle body myself with cloth and a little petrol as I could not get a throttle body cleaner. Then I relearned it after that. But I'm not sure the problem is entirely fixed as it still is sluggish sometimes..and idles high attimes
Cleaning the mass airflow sensor with MAF cleaner worked for a couple weeks and it improved pickup and reduced engine ping, but it returned a couple weeks later.
