Okay. Do you have a scan tool that we can check for codes? If so, are there any codes?
Next the fouled plugs and black smoke are a result of too much fuel. So if all cylinders on that side are fouled the same the we need to look for things in common on that side that could cause over fueling.
This means we need to monitor o2 sensors on both banks and go from there. Clearly the o2 sensors should reflect the rich condition so we need to confirm this first. Make sure you put new plugs in as well. Thanks
