Instant running rich

If your car is running fine one day and the next it starts running rich what would you look for relative to sensors, MAP, TPS, Air temp???

All of the above. Could also be your air temp compensation maps since it's been up and down like a pogo stick around this area lately.

Also, runaway fuel pressure, your fuel pressure regulator could be bad and is letting all the pressure from the pump get by.
