    Hi everyone, I bought my first ever Toyota and have been driving it now for two and a half months. It's a 2005 Tacoma Access cab 4X2 4cyl that I bought from a co-worker that retuired. I use it for my job as furnace technician.
    I have a couple of questions about it. 1. I notice that it revs really high when i start it in the morning. Is this normal? It revs upto 200+ RPM and stays there for a while. Now i've driven a lot of different vehicles but for the last 13 years it's been Ford products. In addition to the Tacoma I own a 2000 Ford Excursion Diesel. I know my diesel is designed to kick up the revs after start up to maintain the proper pressure for the fuel pump, but it only goes up to 1000-1300 RPM. Is there a reasoin why the Tacoma revs so high? If this isn't normal how can i adjust it?
    This leads me to my second question. How many KM (miles) do these trucks get to a tank of fuel. For 65 liters of fuel I get about 500Km give or take. Is this normal? Does the high rev on start up have any bearing on this?
    Thanks,
    GD

    That fuel consumption seems high to me, I get 540km to 65L with a V6/4wd/Auto. 480km if I drive in the city/short trips only.

    The revs are normal. They drop pretty quickly and I doubt that has much of an effect on your mileage.
    Mileage seems a little low for a 5 lug.

    I think the high revs is the ECU trying to warm up the cats quicker for better emissions?
