so I think I found out what the problem is as I was looking everything over I couldn’t help but notice this little guy broke off at the bottom could this be the culprit?

Cuprit for what?

That is not going to effect the running and driving of the car.

Time for a valvecover gasket kit after a trip to the junkyard for new valvecover bolts.vtec 92-95 and all D motors 96-00 will share those same 5 bolts, 2 long, 3 short. Get spares

OBD-0 (pre-1992) injectors are the problem-child. They're low-resistance injectors designed for earlier peak-hold injector drivers. Honda did a work-around by adding a resistor inline with each injector (they're all lumped together in one box) which limits the amount of current going through the injector and the ECU's injector drivers. Low-resistance injectors could probably handle no resistor box, though they're not designed for plain 12VDC operation so overheating could be an issue... They'll be relying on fuel flow for cooling. The injector drivers are not designed for that level of current and will heat up. Semiconductors and heat do not get along well (probably why the injector resistors are in a separate box). Even if they can handle the current without blowing up, the heat-cycling will eventually kill them.

low impediance will not hurt the fuel injectors.

It is components inside the ecu that cannot handle the lower resistance.

How do you think peak and hold injectors work? The resistor box isnt for the injectors, its to save the ecu.

that's just a valve cover bolt. only thing its gonna effect is oil seeping from under the valve cover.

you might want to check your local pick and pull for a 96-98 harness.

maybe some y8 injectors

This is the idle screw that I removed as you stated it shouldn’t look like this should it?
Looks like somebody covered it with RTV sealant, but otherwise that's right. Clean it off before you put it back.

How do you think peak and hold injectors work?
An initial high current pulse to open the injector quickly, then lower current to hold it there. It's not that uncommon with solenoids, since magnetism is one of those exponential functions. The force exerted on the armature is much lower per amp of current when it's in its relaxed state compared to once it's moved to its excited state. So, you give it a peak-current pulse to get the armature (injector valve core in this case) moving, then drop off to a lower holding current once it's gotten where it's going, or even just once it's moving.
You need that low coil resistance to get the initial peak current through the injector, then it's up to the driver circuit to limit the hold current - resistively, by PWM or whatever.
Actually, a poor-mans solution would be to put a capacitor in parallel with each of the current-limiting resistors. When power is first applied to open the injector, current would flow through both the capacitor and resistor, but the capacitor current would fall off quickly as it charges up. When power is cut off, the capacitor would discharge through the resistor. It would still expose the drivers to that peak of current, but not constantly which generates most of that extra heat. It should reduce injector dead time in tuning.

only if it is running the Y8 ecu, but then it would run like shit with the Y7 camshaft and no vtec. it would run super lean given it is running on low cam profile, yet has full valve lift of the Y7 camshaft

Keep this in mind. If it is running the Y7 ecu, there is absolutely ZERO reason to be running injector adapters, as ONLY the 96-00 Y7 injectors with their 190cc rating and specific dwell specs can be run properly.



Check the tailpipe for fuel smell at idle or under minor throttle

That's not how VTEC works. The engine doesn't spontaneously gain and lose displacement when VTEC engages and disengages, and the cam profile isn't going to throttle the engine until he's bouncing off the rev limiter. He shouldn't run a Y8 ECU on a Y7 because the fuel maps depend on the injectors, and it will throw a CEL for the solenoid valve as soon as he revs over 5k RPM.

It will run lean. If he is using a Y8 ecu, it will be expecting a LOW cam profile of a D16Y8 camshaft, which flows significantly LESS air than a Y7 camshaft profile.

It is not rocket science. You feed an engine more air than the ecu expects, its going to run lean.

Plus, I have experience doing this very thing, while waiting on a delayed rebuilt Y8 head in an older project.

These things don't have a maf sensor to determine air flow, and thus needed fuel, the larger lobes of the compromise y7 cam WOULD cause it to run lean on lower map if the y8 ecu were in use, this would be only partially be corrected by y8 injectors, while it would get rich up top, if say, the vtec pressure switch were jumped to allow the ecu to run the vtec map on the top end. The y7 injectors have enough flow capacity to handle the manifold swap, header and exhaust, and shouldn't need changed until or unless cam and ecu are changed for tuning. Most likely result of switching injectors around to unknown is bad quality or no idle. Might be worth sourcing a set of stock y7 injectors from the junk yard and popping them in, see if that corrects the stalling issue.
