Ok guys i need some help with this. My zenki has 157k miles on it and i have replaced alot of parts including BMC,spark plugs,all sensors etc. The problem is is that the engine light comes on and tells me that the BMC is malfunctioning when its braking like it should whether the light is on or off, The 02s are bad and cylinders are blown. Now i did a CT and it has good compression for all cylinders. So anyways i just recently got it cleared of all codes and the light went off and this was 3 weeks ago. Now the lights back on and its the EXACT same codes. What am i suppose to do,replace the new parts with new parts again or pull the light bulb out?
