Welcome! It's very unlikely that the two issues are connected, but you won't know for sure until the codes are read out. The TRAC light (and Stability) often accompanies a number of CEL events, as the system is smart enough to want to protect itself. Traction control and Stability control operation require a lot of engine management (throttle, ignition timing, etc.), so if there's misfires or other events happening, the ECU is smart enough to know not to take parameters into a potential engine damaging mode.
