93TurboSi

on a perfectly good map i have noticed that my wideband is only reading around 10.3. even under hard decel which usually would put t off the chart lean it still reads 10.3. I checked the calibratin accoring to the AEM manual. and with the sensor unplugged i get 3.99 - 4.01 volts which tells me 2 things A. thegain is set properly and B. that everything from the sensor plug back seems to be working. does that mean my sensor has become clogged dirty and fouled?

Anyone else have these sysmptoms with their uego and ems?

Try another map or lean out your current map and watch for changes. If the engines "pitch" is changing..along with rpms, but your A/F is the same, then you've got a problem.

10.3 is what my readout says when the unit is initializing. You must be stuck in the initialization mode? Try unplugging system power from it to erase the memory.
