Started the car today for first time since the fall..

I'm running a termX, and the afr is defaulted lean at 35.6.

The car is stored inside(not climate controlled ) with a battery tender

My assumption is the wideband took a dump but I wanted to check here to see if there's any common quirks that happen with the termX after sitting for months

Thanks

What wideband? I have an Innovate that needs calibrated every 6mos.

Run the recalibration for the sensor, I think is what he's implying.

You should be able to find a procedure to do that with the Termi X.

So with a quick Google, it appears that the termX is pre-calibrated for the Bosch sensor and there is no stand alone cal to run

Call Holley. They may have some procedure to help you determine if the sensor is bad or if it's something else.
