O2 sensor issue
When I drive her HARD I get P0131 P0151, o2 low voltage. Can drive all week with out the codes, go over bumps with no issues.
I am assuming that I have a loose connector or short somewhere.
But being new to the fbody world I am not sure where to start.
Thanks in advance for all of your help
What does "drive her HARD" mean? (I'm almost afraid to ask that.) Does it happen every time you "drive her HARD," or is it just intermittent?
It is intermittent. May have found another data point, twice i have heard spark knock right before i shift. Going to check fuel pressure under load tomorrow
The thing is that the MIL is thrown when the problem is sensed for over two minutes. Maybe your throttle body is sticking all the way open, or something like that?
What is a good high quality pump?
