Got my 784's in the mail yesterday, Did a injector flush on my own to make sure everything was working with them. Heres my set up, post yours! For power, I just rigged 2 wires to get power to the injectors, pushed the alcohol thru them, and they sprayed clean. cant wait to get them in. someone I know just did it to an older xj, and it definetly made a difference. I drive a 2000 and it seems to run pretty smooth already.

I drive a 2000 also which vehicle would have those injectors in them? Also how exactly did you flush the injectors? I really been wanting to do this to mine for a while but I don't know enough to do it

2.4 Dodge stratus has them, those are common cars. they are 784 injectors. I used an IV extension, and 2 boluses. heated up one end of the bolus in some boiling water and fitted it to the top of the injector (end by the electrical plug) twisted my extension onto the syringe end of the bolus, and did the same with the other bolus (the big one). then i hooked up power to the injector, and pushed isopropyl rubbing alcohol thru the injector to make sure they sprayed good.

And for power you did like a 12v and some alligator clips?

yea, just make sure you got the rubber covers on em so they dont cross power and ground. i had a battery laying around with a connector that actually happened to fit on the plug on my injector. it was an old battery from a portable suction unit or something, but it plugged right in. i believe you only need 9 volts for it to open up.

Thanks I'm trying this next week when I go to the junk yard

Finished this two days ago, but here's the setup I used. I was unable to find syringes with the time I had, nor small tubing


- small tub for catching fluid, let injectors soak in SeaFoam for several days in this as well
- injector stand bent out of a coat hanger
- old injector O rings


- 9 VDC adapter from work (there were 12s as well but this thing read 13V with no load on my multimeter so figured I'd play it safe)
- SPST momentary switch interrupting +9VDC from adapter
- EV6 connector from JY
- crapload of electrical tape, all wire is from the wallwart


- 1/2" clear vinyl tubing, pretty maleable stuff, slips over the old O-rings easily
- 1/2" barb to 1/2" MIP, 1/2" FIP to 3/8" barb, added a small hose clamp due to a leak at pressure (SeaFoam in the face for the lose)
- 3/8" clear vinyl tubing
- Pump assembly from a general purpose $2 spray bottle (actual bottle broke lol)

Was blasting carb cleaner and naptha through these and they misted up pretty good, I did a few cleans with SeaFoam (backflush first) so that I could actually see if all 4 holes were moving fuel. The SeaFoam was thick enough I could see the individual streams.

Not pictured are misc screw drivers, Dremel with a plastic wire brush, tooth brush, Seafoam, carb cleaner, naptha, electrical contact cleaner, Q-tips, and a whole roll's worth of dirty paper towel from when I accidentally tipped the whole thing
