First z and I need some help please!:(
 

So I just got my first z let alone Nissan and I love it. But today I was out driving and was beating on it a little, not to harsh. And I come up to a stop light and I notice my idle is at 1500 and I ignored it figuring it would kick down so I drove a few more lights normally w.o speeding or anything and it stayed the same. So I pulled over and turned it off and right back on and it was fine but when I went to leave it sputtered a little bit in first and second zoo I kinda punched it in second and it cleared up and it was fine for the rest of the night. My friends car( the one who talked me into buying one) sputtered and I found a bad coil so I replaced it and it fixed it but it happened to do the same thing again and the next time it was his injector. So I'm a little confuzed on where to look or what to do. I was raised on hot rods so the computer cars are kinda diferNt to me. And if it helps my car didn't throw a code or anything. Thanks a ton

Anything would help please. No one ever replies to these things when I post on em lol. Am I doing it wrong?

No, you are posting late at night, well where I am at anyway. Just be patient, and somebody will be online in a few hours to help you. If I had anything to contribute to help you. I would, but I don't. I don't want to lead people in the wrong direction. Good luck though, hope you get the problem resolved. ;)

First. Relax.

Second. Check your injectors. Then should all ohm out between 11-14.

Assuming you own a 90, the injectors are probably on their way out if they arent bad already.

From my experience with failing injectors, once you hit like 3000ish it doesnt really bog anymore and the motor balances out a little bit.

Check the injectors.

Check for fuel pressure also.

The coils do go bad sometimes but that isnt the case that often.

I will do this tonight thanks for the tips. I will let you know what they read ect. Also are there any rear hub assembalys that are interchangeable like s13 or s14 cuz my rear driver bearing is clicking. Or can I press the bearing out of a 13 or 14 hub and put it in my hub?

You would have to check the compatibility. This is a 300zx forum not an s14 forum. Maybe people on the Nico boards might know.
