[QUOTE="jarance, post: 355090, member: 21"] All MAF are basically the same. It works by 2 wires system. it the wires are dirty, then the air flow reading is affected. Cleaning the MAF will enable the MAF to detect the speed and air temperature accurately thus enable proper combustion by the ECU or DME. Of course, the outcome of combustion is monitored by the 2 nos of O2 sensors. The ECU will then adjust the firng/amount of fuel injected to compensate CO and O2 detected. [/QUOTE]
