Replaced my headgasket and alternator. Started the car and had a weird problem. With the Wideband plugged into the back of the AEM the car ran like crap. sounded like it was missing and loaded with fuel. As soon as i unlugged the sensor from the back of the aem the car idled and ran fine. So i assumed i needed a new wideband. I Bought a new one and it still does the same thing. any ideas? Also the map was never changed and the car ran perfect before i blew my headgasket and the wideband was reading fine through the AEM.

Also in AEMpro the 02 #1 is stuck at 18.3 or something like that and doesn't change. The o2 #1 volts is pegged at 5.00 volts and is red.

Thanks in advance,

ERIK

 

Smell the AEM maybe you fried it
