emissions MD

would o2 sensor spacers make vehicle "not ready" for emissions test. i have a 2020 mustang gt with long tube headers with high flow cats, threw cel codes, o2 sensore spacers solved that problem, now car not ready for inspection noting o2s and htr monitors not ready. have done drive cycle. I am new to the forum so if this has already been covered, please referance thread. thanks

I'm sorry I don't have an answer to your question.
As for the inspection, many states allow you to have 1, 2 or 3 monitors read not ready. In my area, as long as there's no CEL light on you'll likely pass.
Just be aware that even if everything is perfect and a visual inspection sees the spacer you will fail.

In MD inspection is once and done, right? Esp in your neck of the woods? Ask in the geographic section of forum. Most members are a lot closer to DC or Baltimore but someone might be that far out.

I lived in MD a few years ago, as far as emissions go, they just hook up to your comp port, check for failed codes, run a mirror under the length of the car and off you go.

A trick we used to use was to reset the codes just before we pulled up, they would quick check it and off you'd go.

Things may be different now but I never heard of anyone failing for a "not ready" code.

currently i did not fail. it just indicated that some monitors where not ready due to drive time. if you clear the code all monitors go back to "0". now you have to go thru a drive cycle all over again. no vissial inspection just plug in. I go to self serve kiosk. Thank you for all the input.

Try going to an actual inspection station. I failed before at the kiosk with just a tune and manifold swap, but I passed a week later at the inspection station.
