I have been working on this car for some time now, replacing any part that I think is failing or has failed. I just started to dive into the computer systems to address the check engine light that has had me distracted. Code 43 knock sensor(ESC), replaced that. Also replaced the thermostat and cooling fan because it needed that. The light still comes on and when it does the engine looses about 20-40% of its normal power and when the light is off it returns to normal. Should I look into the EST or the ECM or is there something completely diffrent going on here I do not understand? Thank you for your time.
