Scotty,
I have a 1996 Chevy C-1500 Cheyenne with the 5.7L 350, Automatic. I keep getting the P-0175 trouble code for a rich condition, I have already upgraded from the CPFI to the MPFI, changed out the MAF sensor, the Coolant Temp Sensor, all of the Oxygen Sensors and this code keeps showing up, any help would be greatly appreciated!
Respectfully,
Jon F.
Many things can make a vehicle run rich it could have a problem with fuel injectors leaking I could have a problem with fuel pressure regulator I can even have a problem with the ignition system not firing correctly. The best thing to do is pay a mechanic like me to take a road test with his fancy scan tool recording the information then he analyzes the information after the road test to see what is going on because there are too many reasons of the vehicle can run rich you don't want to just guess could be a few bad injectors could be all could be a fuel pressure regulator lots of stuff
Thank you much sir, I will do that this week.
