I have just finished installing my trd supercharger. Rough idle, almost stalling. I checked all the vacuum lines that were involved during the install. CEL turned on with “multiple misfires” and misfire codes on all cylinders. After driving for a little, the rough idle went away but then p0125 CEL followed. I have changed to 91 octane prior to installing the supercharger as well as putting octane booster just for good measure. I also replaced the spark-plugs to something a little colder as per some of the supercharger threads.
Which o2 sensor is the code usually associated with? Could it be dirty fuel filter? It ran fine prior being supercharged. Could it be coolant sensor by the oil filter? Anything i could be missing?
Thanks
