It should go much higher, unless the 29.4 we see on the log above is a maximum possible reading for OBDII. The reason I say that is because this car completely shuts off fuel above 1500 rpm and off the throttle (in gear). Therefore, off the throttle would be basically an infinite AFR since the fuel portion of the ratio is zero.
