Hello everyone,
I have a problem that is infuriating me, I would be very grateful if you could help me.
My 1997 Tahoe Sport, P0300 (then I realized p0305 and p0307), and p0172 and p0175. And it starts hard.
The vehicle runs with an incredibly rich mixture. The exhaust is black, and when I load the gas, it throws black smoke.
When stopping at lights, it shakes a lot.
Only spark plug 5 and spark plug 7 have carbon buildup.
Thank you in advance for your help.
