I thought about that too. Having the injectors unsealed could give the air/fuel mix a shortcut straight to the throttle body. It's possible. I think he'd have some other major symptoms though.

I have a fairly negative opinion of these fuel injectors that supposedly have better spray patterns. I tried some injectors from Flamethrower and my truck ran like crap. He sent me another set and same result. I threw the stock injectors back in and it ran perfectly.

Oh, that is surprising and unfortunate. The Flamethrowers in my 91 Pickup with the 3VZ-E engine did amazing. He sold so many of those sets. It even increased MPG's. Sorry to hear that the 5VZ-FE ones were no good.

I'm sending my original injectors to MotorWest to be cleaned, then will put them back in as soon as I get all the gaskets and crush washers delivered. Can't wait to see what that does to my LTFT (not to mention the fuel in the TB).

I think it will fix your problem. Toyota definitely put that bottom oring there for a reason, it was even on both injector designs..

I think you'll be quite happy with the results... Stock Toyota/Denso fuel injectors are very reliable, but can get dirty. A good cleaning (not just a bottle in the tank) does wonders in those situations.

Most of the good cleaning is replacing the inlet screens. They are a very low micron.

@ Spiker Engineering
Sorry for your woe's, Thanks for the possible What not to do thread.
Good info, Injectors are in my future Oside MotoWest experience worth hearing!

My pleasure, I'm always happy to share any good tips I learn along the way, even if its via the school of hard knocks.
I'm still withholding my final position on this until I get the cleaned OEM injectors back in, then we'll see .

My Saturn always runs negative fuel trims. -10 to -15 at idle to -3 to -8 while driving.

Yeah, watched mine because of this thread. ~-13 at idle and LT pretty much 0 at cruising speed, ST bounces around by 1 or 2 % as expected

Mine is pegged at -18%. I might have been OK with it if it weren't for two things: 1. it was right at 0% before the fuel injector change, and 2. fuel in the TB.

Plugging the idle air assist didn’t solve it I’m guessing.

I forgot to report back on that! I disconnected the hose, plugged the hose and capped the IAC valve tube, and drove around.
My LTFT didn't change (even after resetting the ECU). But the fuel in the TB was gone.

Have you noticed any difference in mileage with the new injectors? Or is the 4Runner garaged for now?
