Well put 200 hard miles on the Explorer after the TSB....... tried as hard as I could to get the smell and the co2 detector to go off..... nothing..... and last week I would have had to roll the windows down........ I'm not saying it's fixed, but in my case it seems to be so far.....
What type of equipment were you using? I was looking at the Pocket CO 300, but at $149/ea, it's a little pricey to buy a few of them.I've measured as high as 19 ppm CO along with the smell after hard acceleration.

I want to get a decent battery operated CO detector with display to check all of my vehicles, but the exposure limits seem to vary greatly as to what is acceptable.
OSHA says Maximum permissible exposure in workplace is 50ppm.
EPA has set two national health protection standards for CO: a one-hour TWA of 35 PPM, and an eight-hour TWA of 9 PPM.
Kidde says "For a person to begin feeling the effects of carbon monoxide poisoning, they would need to be exposed to a carbon monoxide level of 50 parts per million (PPM) for eight hours.". According to Kidde it takes 10 hours to set of their alarms at levels of 40ppm.
Do you recall any of the readings from your home furnace or water heater? Have you directly measured CO levels at the tailpipe or near streets with varying levels of traffic for an idea of the CO levels you may be exposed to throughout your day for comparison purposes?The highest I have seen is 19 ppm. It takes several minute to dissipate. Sometimes there's no smell or CO after hard acceleration. I always have the climate control on auto. The meter has a max mode to keep the highest reading in the display, but no total or average functions. I see maybe 5 ppm sometimes under normal driving, but usually 0 to 3. The meter is accurate to about +/- 5 ppm, so that doesn't necessarily mean there's CO, but I have used it in other cars and never saw anything but zero.
I would think it would vary greatly depending on what traffic conditions are, what outside air quality is like, and other factors. If you are in stop and go, rush hour traffic in an area with air quality issues and the HVAC system is pulling in fresh air, I would expect it to be worse than being in a rural setting with good air quality. My meter is supposed to arrive in a few days and I'll be running some tests around my house, workplace, all of my vehicles and when I'm out and about to see what kind of readings I get.Does anyone know what are the acceptable PPM readings inside a vehicle when being driven? I am about to purchase a CO Pocket Meter and would like to know. Thanks.

Assuming there aren't any issues, I hope my furnace/water heater are also 0 or very close to it. My furnace had developed some flame rollout issues likely due to a cracked heat exchanger, so it was replaced not long ago with a new one, but it hasn't been tested.I got zero at my furnace and water heater. They have exhaust stacks so should be zero. I have measured CO in the garage after I started a car (garage door open) and got around 30 ppm.

Remember, untreated carbon monoxide (parts per million) from exhaust leaks before treatment of the catalytic converter is about 30 times greater or so than those concentrations after treatment of the catalytic converter. It very well could be a combination of both tail pipe exhaust as well as exhaust from manifold leaks, certainly not sure. Like I said I'm going to let this play itself out now that the experts are working on it.
My only issue with your hypothesis is that, although it is possible for vehicles to have QC issues, the probability of that happening over tens of thousands or hundreds of thousand of vehicles over several years has to be statistically low. If it isn't, then one would think the issue would appear in other Ford vehicles using similar assembly procedures/components/materials, and even at other manufacturers....either way it is entering the vehicle via the many holes and seams that Ford left unsealed around the rear end and underbody.
