    This "problem" has been going on for about 1 week now, it's been super cold here in Boise too, but that has never hindered my '98 Tacoma from starting and running before. These engines, I swear, are some of the strongest cold weather starting engines built and they warm up quick too. I've owned a Toyota from the day I started driving.

    Anyways, when I start her up cold I let the engine warm and the temp gauge go up some. I'll drive it to work or whatever, but when I turn her off, say like to fill up with gas, and then restart her (warm) the engine starts, but idles super low (<500?) and kinda rough until I give it some gas and drive for a little ways again, then it idles fine at the stop light/sign.

    Any suggestions what's going on? Fuel pump going bad, sensors? EFI thing?

    You may have a leaking fuel injector.....But....that would also affect a cold start too......Hmmm..
