    I have a 2001 tundra access cab 4.7 a/t 4wd. 2 owners 208k miles. Starts and runs fine but dies when you put it in gear. Kinda like lugging down a manual shift. Idle seems normal about halfway to 1k mark.
    My question is, how do I test for blockage in the coolers ; both external and radiator portions.
