1990 deluxe 4x4 codes
OK I have used a paperclip in the diagnostics box and counted the codes on the check engine light. I cannot figure out what to do to find ou twhat they mean... it blinked 2 times then pause then 4, then long pause then 2 then 5, then long pause the 2 then 6, then long pause then 3 then 1 so if I understand this correctly is this 4 separate codes? 24, 25, 26, 31? or is it a long code with different #'s? can anyone help me to figure out where to read up on this? or at least let me know what the codes mean? THANK YOU!!!

It would be the 4 codes and they would mean; Code 24 Intake air temperature signal fault, Code 25 Air/fuel ratio LEAN, Code 26 Air/fuel ratio RICH, Code 31 Air flow meter circuit or Vacuum sensor signal fault

Thank you for your assistance everyone. would the air flow sensor throw codes for air fuel mixture? why would it read both lean and rich? I already figured I wold have to change the air flow sensor. is there a fuel mixture sensor I should look at also?
