P0171 code

Yoda2001 · Jul 11, 2020

Hello,
Ive looked around at this but im wondering if you guys might know some more with these trucks. I recently bought a new to me 2001 toyota tacoma extracab with the v6. I read the codes since the check engine light was on and it read p0171 which means the left side of the engine is running lean. Im not sure what this is and how i fix it due to the engine seems to be running good, no weird noises and starts everytime. It did come with a throttle body spacers so im not sure if thats whats doing it? Also is it okay to drive with that code? Thanks!
