i have a 99 tahoe and the ses light keeps coming on reading po340. i replaced the sensor and still, same code, same problem missfiring. how to i fix this problem? i checked the wires, nothing wrong, i reset the code with a scan tool(a cheap autozone tool but it serves most of my small diy needs) but the light still comes on. any advice? thanks

Might have to give up women if you did that,LOL.
