Just got the call from the injector cleaning tech, 1 was totally clogged, 2 very low output, the rest working but out of spec, He was able to bring them all back to life and in spec, should have them back soon to reinstall.

I sent off a set of injectors from a 86 the engine had a rough stumble when idling and warmed up.
Anyway the tech at Witchunter gives me a call and says so what do you want me to do with these injectors?
throw them out or send them back to you, they are all junk.
Turns out these were Accel injectors.
Though they looked new the PO had gone and bought lots of less expensive parts to fit to the 86 this made a lot of running issues appear.
After some searching on Ebay I got a set of Denso/Ford rebuilds from a 5.0 Mustang plugged them in and the engine ran smooth as glass.
I hope the injectors clear up your running faults

These are the stock Bosch injectors with 60K on them, so they should be good as long as they are kept clean, will change out the fuel filter before I fire it back up.

My car had similar symptoms until I plugged in the rebuilt LH box. Try yours in another car and see if the symptoms move with the controller. If the refurb'd injectors don't do the trick, this might be your next step.

Thats one of the first things I did, replace the plugs with Bosch copper 7900,
it was still running terrible, so I started to listen to the injectors
and noticed at least 1 was not clicking so I pulled them all and sent them
out to be cleaned, should have them back on Saturday to test out.
