    Hello,

    I replaced my throttle body on my 1999 Toyota Tacoma and now when I start it it will run for about a minute or so very rough and then die. Any ideas.

    mine did the same thing when i installed my TBS i knocked a hose loose in the back of the motor and wound up flooding it....i had to take out the EFI fuse and turn it over so it wouldnt dump anymore fuel in....then i put the fuse back in and it started with a little gas

    3.4 and Toyota said there was a groove in the throat and the TPS was not reading correctly.

    Was this a new or used TB? It sounds like your IAC valve needs cleaned.
