HELP! Evo 9 AEM V2 idle surging issue
It does stop when its bolted up but it completely closes off when I start the car on the AEM. With the stock ECU it doesn't
Here it is guys all fixed! My AEM EMS is using my Zeitronix wideband sensor as the primary o2 sensor. Found out the sensor was dieing so I replaced it with a new one and bam. Issue fixed!
Thanks for all the help!

Alright guys. I thought I had fixed it but it came back. Seems like the car acts up more when a lot of battery power is being used. I changed the alternator and got a new battery but it didn't help
Here's a log I did at idle for a few minutes. Towards the end of the log I got it to surge a lot when I wacked the throttle real quick with the headlights, high beams, heater blower motor, and interior lights all turned on. If I turn all of that off it fixes itself pretty quick
