Ok, I have a question. I already did a search but didn't really find any concrete advice. I have a 99 T4R, 4x4, 3.4 V6, auto with 265k miles. Yesterday as I was driving to a favorite mountain biking location I came to a red light kind of abruptly because I was cut off by some jacka$$. Anyway, when the light turned green I hit the gas to get around the above mentioned person but my girl would hardly move. The engine sounded a little strange, not quite backfiring but sort of sputtered, almost like it was in a "limp home", the rpm's wouldn't really climb and just slowly started to move. I got off the gas and just lightly accelerated until I could get over to the shoulder but by then it started to run almost normal. I was only 1/4 mile from where I wanted to go so I just drove it to the parking lot and shut it off. I re-started it and revved the engine up, all was good so I drove it around the parking lot and it seemed to be ok. The CEL never came on or blinked. No smoke from the exhaust, nothing. I popped the hood and checked the vitals, everything was in order, fluids all good and clean, plug wires on and tight, no leaks of any kind. After my bike ride I fired it up and drove it home down the freeway at 75 mph with no problems whatsoever. I haven't tried pulling codes yet, I plan to take a look tonight when I get home. Here's a list of all of the recent maint. items already performed- oil and filter, trans flush, plugs, wires, fuel filter, air filter, Seafoamed. I have put about 200-300 miles on it since I did all of the maint. It already has new catalytic converters and O2 sensors and the timing belt was replaced 25k mi ago. The only thing I can think of is a possible fuel starvation, possibly the fuel pump may have had a hiccup or something. Anyone have any thoughts?

Yes, I cleaned the MAF too. Do you by any chance know where the fuel pick-up is located inside the fuel tank? I had about a quarter tank of gas left and when I slammed on the brakes and came to a stop I was on a slight incline. I'm wondering if maybe the remaining fuel sloshed around enough inside the tank and possibly starved the fuel pump...
 
I once had a loaner BMW 5 series, 1995, and I was driving up a large mountain and it refused to down shift which eventually led me to pull off the road, turn it off and then back on. It had those same symptoms. Maybe your quick stop didn't allow it to get into first gear and was stuck in a higher gear? I could be completely wrong though.
 
Wow that's funny. My 4runner did the EXACT same thing at that same mileage. It only did it once. Now I'm just over 270k and it hasn't happened again.
