I'm ot sure if the MAFS is working right. But I did not touch it, just spray. I just wondering if the sensitive electronic cleaner is ok for MAFS? I did not know MAFS cleaner before I saw it in store last week. So, I used to use sensitive electronic cleaner to clean the MAFS several times. IF the MAFS is bad, will the check engine light come on? My check engine light did not come on. I will try the MAFS cleaner first, then coolant temperature sensor.
