Delasangre4231 Posted October 3, 2009 Share Posted October 3, 2009 I have been looking in the FSM and cant find anything on the AFM. I have already gone through the diagnosis stuff and figured it is a faulty AFM, but what I want to know is what all the model numbers correspond to... The one in my car is the A31-622-420, but I want to verify that is the correct one for the car I have because there are like 14 options for a reman. 1983 280zx NA 5-speed Quote Link to comment Share on other sites More sharing options...
roger.svoboda Posted October 4, 2009 Share Posted October 4, 2009 did you check the fuel injection bible and/or atlanticz site (might be the same) you might find some insight in reading that. Quote Link to comment Share on other sites More sharing options...

eec564 Posted October 4, 2009 Share Posted October 4, 2009 Why do you think you have a bad afm? Sometimes they just need tweaking, after years of use the springs in them wear out. For part numbers and year/model application cross reference use FAST. -Eric Quote Link to comment Share on other sites More sharing options...
