Just installed a AEM 30-4110 wideband. Worked great for the first 3 minutes and then it pegged full lean and 3 dashes appeared on the display and stays that way. I contacted AEM and performed their "tests" which resulted in them saying the gauge is most likely bad. Now I have to send the gauge and sensor to AEM for testing. Purchased this brand new. Anyone else had this issue? If so, what was the resolution? Thanks.
