Lets not argue, you are reading 2 digit codes, OK fine, that used to be EEC IV. Don't have a clue about OBD 1 or when it came about. The same tester was used. The 22 used to be the MAP sensor, believe its called MAF sensor now. Am lead to believe both measure the density of the air and in later generations, the volume of air being processed into the intake system. Wish I could be of more help besides just part changing ideas.
