danman Posted August 29, 2004 Share Posted August 29, 2004 I finaly fixed my MAF problem. 84-87 300Z Mass Air Now I am wondering what the screw located underneath metal plug on MAF does? How do I adjust? (I know I just turn it, but what method is used to properly tune?) The screw is behind metal plug next to connection terminals of MAF. Previous owner drilled out the plug to expose this adjustment screw. Quote Link to comment Share on other sites More sharing options...
mc Posted August 30, 2004 Share Posted August 30, 2004 ...it allows the adjustment of the rich/lean of the fuel and air....dont adjust if the red/green of the ECU are flashing in sync. throughout the rpm range. Quote Link to comment Share on other sites More sharing options...
danman Posted August 30, 2004 Author Share Posted August 30, 2004 Thanks for the reply. So this should be done on a dyno then. Quote Link to comment Share on other sites More sharing options...
