Default 97 Nissan D21 Hardbody Stumbling/Idle issues

Hello, I have a 97 Nissan D21 XE - Ka24e Motor, 2wd, 5-speed.

146k miles Original motor

Essentially the truck runs good 95% of the time, when giving throttle.
The other 5% of the time, it stutters during acceleration.

It will not idle well, if you release throttle, it will dip down to 200-700rpm and want to die, (sometimes it will die), and then hold proper idle for a few seconds before dipping again.

I have done the following;
1. Replaced all vacuum lines
2. PCV
3. Cleaned IACV
4. Cleaned EGRV
5. Fresh Plugs and Wires
6. Fresh Dist. Rotor
7. New Air Filter
8. New Coolant Temp Sensor
9. Fresh Oil + Filter
10. New Water Pump + Gasket + Radiator + Rad. Hoses
11. New Drive Belts (all 3)
12. Fuel filter

Not all are related to the issues stated, but here is the list.
I have a Scanner, it reads Misfire on #3, and at this point I am not sure what to do next or where to go.
Thanks for the time.

EDITED: to show Freeze Frame data, missing maintanence.

Injector issue maybe. Others here know this motor better. But feels like a fuel issue.

Okay...I have studied your post extensively and have seen your repairs.

First thing: Determine whether the hesitation or miss comes when you are passing someone on a flat freeway...or trying to floor it going up a hill.

This is important.

If it does this stuff on a steep hill, it's a spark problem.

If it does this stuff flooring it at higher speeds cruising on a freeway, it is a fuel delivery problem.

If it is a FUEL problem, either some of your injectors are partially clogged or not working properly....or your fuel pump is getting weak.
It could even be the fuel regulator, or the fuel filter. Didn't see fuel filter on your list. Start THERE on GP. They cheap.

Determine where the miss occurs first, and then let us know. You have to narrow it down a bit.

Actually, the first thing you should do is put a timing light on it to see what your ignition timing is set to.

Second thing to do (if your timing is set to 10) is to pull the codes so you aren't guessing or trying to fix a condition that the ECU is generating. You said "it reads Misfire on #3", but what was that code? The code is exact.

But, make sure your timing is correct before trying to pull codes.

Edited to reflect forgotten Maintanence. I have the Maintanence book that has been kept up to date since the day the truck was first purchased at the dealership, so I can always go through it and name what’s been done as well as the date / mileage it was done.

I don’t usually have a problem once the accelerator is pressed, whether 1/10 or 3/4 engaged. It’s mostly at idle it poops out of whack.

So the other 5% of the time I have mentioned, it’s on acceleration from 1k-2k rom. Once I hit the magical 2k rpm, it’s smooth from there up. When this is the case, which is rare so it’s hard to reproduce, it feels like it’s either being forced too much air, or starved of fuel. I base this on the same feeling from flooded carbs on my dirt bikes.

I’ll have to order a timing light.
The actual code my scanner receives is a P0303 (Misfire Cylinder #3)

That sounds like an intake leak, but Code P0303 could also cause that.

This description sounds exactly like what you are describing:

Look at the fixes listed there for it, too.

classic vacuum leak. not bouncing, but a relatively medium paced rise and fall of the revvs.

This happens because the motor raises the revvs, sees the right amount of fuel/air, cuts fuel and it drops. then the motor sees the wrong mix and tries to adjust idle up to get the right mix which raises rpm.....repeat.

to test the old hotrodders will say to use carb cleaner. i personally like electrical parts cleaner. little easier on the ol plastic bits. spray the cleaner around the intake manifold where it meets the head. if the revvs stabilize, you found it. replace the gasket if you find a leak there. if you are lazy, smear a shitload of RTV on it and let the motor idle to suck it in a little

I have posted my Freeze Frame Data in the Original Post.

There is one hose going from the Air Box to the Crank Case (Engine Top Cover (I dunno what the proper term on a car is)), which has a Crack. As for the gasket inside the Air Box, it is very supple and looks to be in great condition, same goes for the small Metal Spacer Cage looking thing under the Air Filter (for lack of knowing this parts name).

I do not know the inner or outer diameter of this hose to order some new silicone. Nor do I have my calipers near me at the moment. It would need to be very high temp as it connects to the crank case.

UPDATE: just got home and popped the hood for the first time since the idle has gotten worse. There is a definite leak, it’s pretty loud.
Still need to know the diameter of the short hose going from Air Box to Engine Crank Case. Probably 3 Inch hose.

Okay, I found my leak. Its coming from what looks like my injectors gasket, lo' and behold, its on the #3 injector. Behind the fuel rail and attached to the motor. So not actually the injectors or fuel rail, but the gasket that goes to the motor and manifold. If someone can confirm this, I can order the gasket.
Sprayed some soapy water around the noise area, and once located I even felt with my fingers, and can confirm its from the area circled in the picture. It's the Green Parts and under that is the gasket itself.

Under warranty? That's great. Take it in and have them get right on it for you.

Sweet!
