Running extremely rich, help
1j truck it's running extremely rich at idle and normal driving to the point it back fires and shuts off at every light, aem gauge reads 10.0, after I did a ecu reset it ran fine on base settings for a while then issues reappeared.. Could be the oem ecu going bad? Or perhaps o2 sensor since ecu would run on closed loop for some key cycles??
