Oh, and about the fuel pump. I'm still having occasional issues with stumbling and surging. I suspect the fp, and I want to replace it as a diagnostic. I just want help with selecting one. If you had to buy a NEW fp for your GEN 2 with the 3.4L swap, what fp would you buy? What will fit in addition to the 93 4runner? Aftermarket, or one spected for the 2K Tundra 3.4L? I figure while I'm buying a new one, which one would be best for performance and worth an upgrade as such. I'm really worried about this, as I suspect either VERY NOISY injectors, or knocking. I don't want to hurt the motor, and not being about to connect to the ECU for codes makes my uneasy driving it. Anyone's 3.4L have loud injectors under load?
