I had some trouble with a miss that I tracked back to some dead injectors. Now I'm wondering if I have the right injectors and if not, I need help tracking down the correct ones.

What I took out of my '99 4Runner were original brown plastic Denso model 23250-62040. Like these:

What I replaced them with were Denso model 23250-62030, like these:

which were the same part # listed on Rockauto.

Now I'm questioning whether these are correct because my seat-of-the-pants dyno is saying I'm down on power, yet my fuel economy is on par and I'm not throwing any lean codes (which is what started me down the path of diagnosing bad injectors)

Are these correct and I'm crazy? Or do I need to buy new injectors?

 

Either injector will work fine. I've used those models in a 2004 5vz. I've used the brown tops in a '98 motor. Same inpedance, same flow rate (245cc/min) but different nozzle.
