    Okay so I've git 99 tacoma 3.4l. Engine light is on and reads p0171. Running too lean. At a cold start it start great and I can drive around all I want and everything is great. But as soon as I turn it off and then go to start it again while it's still hot, it has a hard time and the idle is super rough for a few minutes and then it goes away. I just replaced my motor at 140,000 miles cuz the block blew. This problem was happing with the last engine, but the whine light was not on. So now that I have this other engine, also 140,000 on it it is still happing. But now a week after the replacement of engine the code has finally popped up.
    I replaced fuel filter and cleaned the MAF but it's still idling recalling rough at a hot start. Any ideas where to look next???
