What is the difference between MAF sensor and IAT sensor?
MAF is an acronym for “mass air flow.” Unlike IAT sensors, MAF sensors measure air volume with temperature at once. An MAF actually measures real air volume so that the computer doesn’t need to guess what it might be.
What can I use to clean IAT sensor?
They recommended a spray solvent made by CRC called “QD Contact Cleaner.” You can get it at Lowe’s and Home Depot, in the electrical area. I got some and cleaned the MAP and temp sensor and bingo: instant smooth idle.
