Injector Question

Just looking for some advice...

I've got a misfire on cylinder 1 that only occurs when I rev over 4k RPM. Starts and idles fine, and then once I go over, it misfires and never recovers. I believe I've narrowed it down to a bad injector (Swapped the injector and the misfire moved to that cylinder).

I'm just curious - is this a symptom of a bad injector - if it gets overloaded and then just stops spitting out fuel? Is it clogging after getting more flow at a certain point? Should I buy a new one or try to have this one cleaned and re-worked? Or - is this something entirely different and I'm missing something?

Remanufactured injectors are cheap from Pelican, so I'm not opposed to that.

1986 NA 944 5-Speed
I've Replaced the Following:
Fuel Pump and Filters and Fuel Rail and Lines, Fuel Pressure Regulator
Vacuum lines, J-Boot, AOS Seals and Hoses
New Idle Control Valve and Hoses
New F9Tech DME and MAF
New Water Pump and Timing Belt
New Cap, Rotor, Plugs, and Wires
New Coil
New Battery



Thanks!
