The fuel injector harness can be removed without pushing in clips. They don't fall off while the engine is running and with a stethoscope I can here them firing. Engine has a lean condition that doesn't throw a CEL code but fuel trims and o2 readings point to lean fuel. All four injectors read 12.5 ohms..also I drop tested them by removing fuel injector harness one at a time and rpms drop on each cylinder. Just wondering if possible poor contact from loose clips might be an issue?

The plastic tabs are worn out. Grab some from the junkyard and splice them in. Any injector harness plug from an OBD1 Civic/Integra will work, assuming your setup is OBD1.

Yes obd1. Thanks.
The prior owner wired in an extended IAT harness that looks to be spliced into the fuel rail harness.

over time, the plastic will deteriorate due to age and heat. I'm sure you can find replacement plugs easily. As for soldering them in, it's simple since there are only 2 wires....one with black stripe and the other solid color.

I pulled a FPR off a junkyard "94 civic a couple days ago and out of curiosity I pulled on it's injector harness..they are on tight. I need to return the FPR this Friday so I will pull the injector harness. Would you say that in your experience if an injectors harness is loose it still works properly?

If the injector harness comes loose and the wires aren't making connection, you will lose a cylinder due to lack of fuel in the combustion chamber (aka top of the piston). It's one thing if the car is stock but imagine if it was a turbocharged setup. Detonation SUCKS ***.
