ltlfrari Posted June 13, 2004 Report Share Posted June 13, 2004 Anyone know what rate injectors are in the 91-93 and 95 3.4 DOHC motors. I am running a 95 engine from a cutlass in a Fiero with a 93 ecm and manual prom. It is running reeeeeeeeaaallllllllly rich and I am trying to figure out if the injector rates were really different.

Canada Posted June 14, 2004 Report Share Posted June 14, 2004 I did a bit of research on GMPD's catalog...........91-93 3.4 DOHC has the same parts number........but 94s have a different.....this *might* be involved with the switch to SFI.....I don't know why it would.....they actual firing of the injector is the same. I should also add, my 1996 Beretta's injectors for the 3100 also carry a third number.....weird........either there IS a difference in the flow rates or the internals of the injectors......or the same part carries a different number (that happens more often than you might think). 17104256 - 91 3.4 DOHC 17090849 - 94 3.4 DOHC 17113572 - 96 3100 Quote Link to comment Share on other sites More sharing options...
