4th Gen V6 - P0172 & P0175

Hi All,

Long-time 2002 V6 Camaro 3800 owner here (5-speed). I've been wrenching on my Camaro 23 years now. That hasn't been a big chore, but I do know the car pretty well at this point.

Recently my Camaro was stalling out and running quiet rough. Using the OBDII, I found rich fuel conditions (P0172 & P0175) along with O2 and other generic codes. I worked through a lot of diferent potential fixes when diagnosing and decided to make a couple repair videos to help others if/when they encounter the same issue in the future:

Diagnosing a Rich Fuel Condition -


Fuel Pressure Regulator Replacement -


Anyway, I am hoping this helps save a few people some time in the future. I couldn't find much on the internet related to this issue when I looked. I plan to keep making videos as I continue to solve problems on my Camaro.

Thanks!
