Timing, vacuum, and carburetor jetting can affect CO levels, keep in mind that high 7% or low will cause high hc readings. set timing to factory setting and adjust carb jets for smoothest idle, probably will slow idle down quite a bit so after that adjust the idle speed screw until idle speed is at normal. you will need to reset after test is done. All settings must be at optimum for burning fuel as co is unburnt fuel, that is why vacuum leaks are not good.
A vehicle that emits high air pollutants; did not pass the national emission standard. The term originated from the Philippines.
A low pass removes frequencies ABOVE a set level. A high pass removes frequencies BELOW a set level. A separate high pass filter can be used to route only frequencies over, say, 80 Hz to your main speakers (if your receiver/processor did not have this function). Then you would set the low pass filter on the subwoofer to 80 Hz to reject signal above that level.
high
Logan Pass is 6,646 feet above sea level.
depends who sets the 'pass level' and maybe what the subject is. 70% sounds high enough to pass though
No, it will not.
No it will not.
I have a 1999 E350 cargo van and it does not require emission testing
You may start to feel dizzy and/or weak. Then if you don't get help or emergency attention and the level of CO2 is far higher than the oxygen level, you can pass out.
