I have an AEM eugo wideband, I didnt see anything in the instructions for calibration

Right at start up the numbers flash around 14-15, as the rpms drop down below 1000 is when it maxes out A/F. I guess I will see what the fuel pressure looks like and go from there because I really dont want to take apart that exhaust again

Its sitting at around 10-11 right now. Its not horizontal but if I do end up taking it apart I should be able to spin the pipe and get it at high noon.

It was working at one point and time. At idle it was reading normal a couple weeks ago but it hasnt been lately. It still drives and feels the same to me. Im starting to think maybe I got some bad gas, low octane fuel would have an impact like this right?

Bad fuel would give you many issues, but that would not be the cause of the exhaust leak. Do you not have your hand held tuner?

According to the AEM webste: We use Bosch 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!

My Innovate G3 was doing something similar recently, I plugged my handheld in & datalogged. The gauge would go minimum or maximum, appx 0v or 5v. Sent the log to the vendor & their response was the Bosch sensor needed to be replaced (least 10 years old). Got a replacement & hope to install it this weekend.

I also added a couple of pics when I blew my head gasket and it was pushing coolant. Just cruising around was fine...for a while.

Wow thats some greasy water. I just checked my fluids and everything is holding up. I think if it really was my head gasket I would be seeing some sort of smoke out the exhaust and losing water which isnt the case so thats good news. The senor is practically brand new but I wont count that out.

I was thinking back to the last time I got gas and I did drive down the block with my fuel cap hanging out. Luckily some guy pointed it out and I tightened it up. Stupid mistake on my part, surely that lose of pressure for a mile didnt hurt my pumps. Could that be the case?

Fuel pressure looks good, sitting around 35-37psi at idle. I guess I will look into trying to find an exhaust leak. Maybe the header gasket or the donut gasket at the collector
