So my car has been down for a few weeks doing a few upgrades, and a heater core replacement. Installing a new AEM uego wideband, and wiring it in to be logged. Also using link to simulate the narrow band signal. Like already stated, I decided to also tackle my heater core replacement. So needless to say, I definitely had things tore down. Heater core jobs can really suck LoL.
So after getting things buttoned back up, I've had nothing but issues get my car running properly again. First I found I had a bad ground at the CAS circuit, and had to supplement a new one. Haven't really found a reason why on that issue. Now my car is idling really high, and then starts surging after a few minutes. Looking at my logs, it's also showing A/F ratio isn't matching what the gauge is saying. And once it starts surging, it goes completely lean to rich over and over. I'm really not sure what to think about it. It could be a bad o2 sensor, but that wouldn't make it idle high, or surge I don't think? Maybe the IAC is bad, but I replaced it a few years ago. Anyone have any ideas here, I'm getting extremely frustrated with this nonsense. Seems like my car's cursed lately.
