I noticed my TCS light comes on after I drive a little while and won't go out unless I power cycle the car but it will come back after a little while of driving. I replaced both front wheel speed sensors. I still have the same issue.
any suggestions?

 

Is the CEL on as well?
Have you been able to pull any codes?
Have you switched the size of your factory wheels?

I suspect it might be the EGR.

 

I don't know what the CEL is. I am still running the factory 205 60 16 tire size. I don't know what the EGR has to do with this

 

Have you been able to pull any codes at all? Did the Check Engine Light ever turn on the same time as the TCS light?
When the TCS light comes on randomly without a Check Engine Light, it commonly throws an EGR lift malfunction code later on. Replacing EGR valve usually solves the issue.
