Where are the O2 sensors? I found one directly behing the spark plugs on the back.

The O2 sensor (2 on V engines) are in the exhaust system pipes before the catalytic converter, the next sensor is the efficiency monitor for the catalytic converter system it looks like a O2 sensor but performs a much different function as far as testing goes. The codes you have follow.

P0420 - Catalyst System Efficiency Below Threshold Bank 1
What does this mean? In most cases it means the catalytic converter is worn out and that is sensed by the catalyst monitor I spoke of earlier.

P0102 - Mass or Volume Air Flow Circuit Low Input
Faulty mass air flow sensor
- Dirty mass air flow sensor (located in the air intake hose to the engine from the air cleaner)
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks

My chevy blazer 2000 ha a p0101 code changed the mass air flow sensor still does not want to accelerate

Hi there:
This code is set when the MAF (Mass Air Flow) meter is not sending the PCM the correct information. This can be due to a bad conection of the rubber intake hose between the MAF and the Throttle plate opening, a dirty air filter, a dirty mass air flow or a bad mass air flow.

Most programmer have you tie into the iat sensor in the mass air flow. this can cause the the iat sensor oto short out.

Hope helps.

My 2005 chevy cobalt will not stay at a constant idle

Well you shouldn't pay to much attention to what some people say . Never use carb. cleaner to clean a mass air flow sensor , they make a special cleaner for mass air flow sensors . And you just spray the sensor an let it air dry ,then put it back together . And as far as dealer's not being able to find this ,i'm sure some may not . Just as any independent repair shop may not . I have thrity years experience at GM dealerships ,started at a Chevy dealer back in 1984 ,right out of a two year automotive technician program . Have worked at Cadillac , pontiac , GMC etc.....
Listening to others making guesses as to what the problem is ,mite fix the problem an then again it may not . There are a lot of electronic componets on your vehicle that could cause your problem , looking at sensor data on a capable scan tool is the correct way to find your problem .

Car shuts off when I stop

Try cleaning the two cross wires inside the mass air flow sensor. (use Q-tip and carb cleaner) It is also possible that your oil pressure switch has a low pressure cutoff feature. If the pressure is low at normal idle, it will shut the engine down. Check oil pressure with a mechanical gauge and if it's good change the sending unit. (check to see if voltage flow through switch stops just at shutdown first though)
