My 1999 TLC loses the ability to apply gas to the pedal while driving, which according to the dealer, can possibly be fixed by replacing the entire throttle body (which includes the sensor) at a cost of $1200 for the body plus labor of about $300-400. I drive the Los Angeles freeways, which is a very dangerous situation if you can't pull over fast enough. It's happened 3-4 times on city streets thankfully, the check engine light comes on, I pull over, restart and it's fine for weeks, until the next time. My mechanic reset the computer which said it was a throttle body sensor problem, but it has returned. I say the dealer could "possibly" fix it, as the real problem may be the computer, which costs $2000 to replace! I have to do something, but before I argue with them and/or go to the expense of replacing it, does anyone have this problem and a better solution? I find it insane that Toyota as a safety issue wouldn't replace it themselves. And even if I do replace it, the problem may not go away. Thanks for any help.
