I have a 91efdx and it starts fine, idles okay, but when i start revving it for a couple seconds it starts to bog down. ECU has codes: 1,7,10,14,16. Changed fuel pump, changed relay, changed o2... my next thing is checking voltage to my injectors. N00B question: I have a pretty complex digital multimeter to test my injectors with. My problem is, I dont know what setting i put it on to test my injectors, EACV, and IAT.

 

You should get a 88-91 service manual (pdf)

all the information you need is in this

hope it help

 

Thank you for the link. I just went out and bought a haynes manual. I tested the injectors, voltage was normal, but i pulled the aux injector out and there was no gas. Then i pulled the main one and very little gas was shooting out... so ive decided im going to use my Si intake mani with all the sensors and ecu that i got for literally nothing... i just had to pull it myself (the perks of working at a scrap yard that your uncle pwns) and im gonna use the 90Si in our scrap yard for the harness clips n all. All these leftover sensors that are pulling codes are mounted to the intake mani anyways haha
