Hey Scotty, Love the videos. Question is:
2015 Chevy (I know, I know) Silverado 5.3l gas / AT with 107451 miles. Had long-term fuel trims pegged negative with a strong odor of gas in the oil. Changed the high-pressure fuel pump, flushed and changed the oil, checked for intake leaks, still have an imbalance between bank one and two by about 2. Full negative reading has moved to 0 to - 3, but still a lack in power and hesitates off the line. No codes. Also, what is the correct or normal reading for o2 sensors on live data?
Thanks!
Chris M.
Well if the data is wrong on oxygen sensors it's going to trip a cold the only way to really analyze the sensors is by hooking up a freeze frame of sylliscope comparing them all to known good waveforms complex stuff. But I know it's often either internal engine failure as they don't make them like they used to or computer module failure where the drivers in the computer don't run the systems correctly it does take a pro to analyze those in person with all this equipment
Thanks Scotty! Have a great day!
