    I have a 2015 tundra trd pro with 105,000 miles I bought the truck with the K and N CAI. I have had it for around 2 years with no issues and recently the check engine light came on with traction control off displayed on the screen. the truck had some issues with idling after the cel came on and also has trouble shifting when your trying to step on the gas a bit like to pass someone on the highway it won't down shift sometimes and ends up bogging out. I ran the codes and its throwing po175 po101 and po172 all the research was pointing towards the mas airflow sensor, I replaced the sensor and that didn't fix the issue I have also cleaned the throttle body and that didn't fix the issue either, I cleaned the filter on the CAI also did not fix the issue. im coming on here to see if anyone else has seen this issue I am debating weather I should replace the CAI with the stock intake. I am also curious what the stock intake on the TRD Pro is. any and all help is appreciated thank you.

    Maybe a vacuum leak. Was the MAF replaced with an OEM one?

    I am wondering if you need a different maf for the cold air intake? Also having trouble finding exactly what the stock airbox is on the trd pro
