If some one can give me sum helpful feedback it would be truly appreciated. My 99 GS 400 Vsc lights + check engine light+ i put my foot on the gas and the car wont accelerate. It was runnig perfect right before those lights appeared. I got it put on a scanner and a throttle positionig code popped up dnt kno the exact code but wht do u think i need a new sensor or i need to replace the whole throttle body?

 

Probably just the sensor. If you've dne any work on the car check the plug on top of the TB. I left mine loose like a dummy when I did my plugs MMAF and TB cleaning. Tore it all back down to realize I just didn't completely click it in. If you've not been working on it, have a mechanic check the sensor

 

yup sounds like a tb issue...
