The other day i picked up an 88 NA rx7. it didn't quite run right so i changed the plugs, plugwires, oil, seafoamed it, and sent the injectors in to be cleaned. Unfortunately the guy i gave the injectors to, so they could be cleaned called me shortly after i had dropped them off to inform me that i had a pair of high and a pair of low impedence injectors. so my question is, can a car even run with both high and low impedence injectors and also which injectors should be in it? i looked around and am getting both answers so if you could clarify that would be great thanks.

 

That all depends is someone wired in resistors to the low impedence ones and your harness is for high impedence. You need to look and see if you have a resistor box around pass side inner fender.

 

I run my car like that. primary 550cc high imp and secondary 720cc low imp. Just had to wire resistors inline with the low imp ones.

 

Normal stock 88 get/got high impedence injectors. No ifs ands or butts. I said STOCK RX-7.
