Thread: Stalls at idle until driven a while

The FSM should list this, I would think that you should be able to put a meter on that wire and see a fluctuating voltage. It's going to be a series of pulses, so your meter may not show the full voltage, but you should see something. If you had access to an oscilloscope, then you could see the actual pulses, but I'm sure that's a long shot.

Sorry for the delay as I finally got around to messing with my car. I rented a kit that tests the injector plugs for signal and they seem to be fine. I then used my multimeter and Ohmed out the injectors. Here are the results:

#1 = 493
#2 = 13
#3 = 148
#4 = 12

#1 is the one that isn't firing. I could tell #3 was weak when I pulled the wire and it didn't drop in idle nearly as much as #2 or #4 did when I pulled their plugs. So I am thinking I need at least 2 new injectors at this point.

Any thoughts for or against these fuel injectors?

What about hitting the pull yard and grabbing a whole bunch from other SR20's for like $10.. at least then you'll know they are most definitely OEM

That would be great but there probably isn't an SR20DE within 2 hours of me. I live in a small, rural area. Jimbo_SE-R, I am not terribly far from Austin. Are there many salvage yards with SE-Rs in your area?

Can be a pain in the ass to pull them, but pack some snacks and make a day of it. Take a meter and test them before you pull, save some time.

Know your yard's pricing up front though, some can screw you on small items if they have some minimum charge. I usually have something larger I'm getting, and anything in my pockets walks out for free. I've overpaid a number of times for parts I didn't need because I didn't have the tools to remove extra bits fully, so to me it all works out in the end.

Same for me. Back a few years ago I used to pull random SR20 parts I sorta of didn't need, and they ramped up the pricing on garbage that was attached to it (wiring harnesses and plastic trim pieces etc) - now I've learned my lesson

There is a Wrench-A-Part up in Belton, down here is another and also an LKQ yard. You typically won't find B13s, but you can usually find a number of G20s, and some 200SX SE-Rs. There may well be other Nissans (and others) that use this same injector, I'm sure there is a cross reference online somewhere.

Wrench-A-Part and LKQ both do a good job at their online inventory, there is also a mobile app and web page for Row52.com for doing parts yard searches which I have found very handy.

Dude, that brings up an awesome point I've been wondering about for awhile. Why are there so many G20's at the pull yards? I mean its not even close to what you'd expect. I was at Harry's U Pull It in Hazleton, PA, like one of the largest pull yards in the United States, and there were probably twelve G20's and like 4 B13's.

Well, we're kinda hijacking this thread (heh), but the B13 was only made for 4 years, but G20s were made from '91 - '02. And all G20s had an SR20 in them, as opposed to being a premium part on the other Nissan models. So it's just a matter of raw numbers, plus then there are the sales numbers for each model, and I'm sure that there were more civics and camrys sold that make finding these a bit harder too...
