I'll bet it's an over-oiled air filter that is contaminating the wires of the MAF. The filter needs to be taken out and washed properly and dried, then oiled sparingly like it's supposed to be. The instructions on the re-oiling kits usually will warn you of this. The MAF wires are very sensitive to be ruined quite easily.
K&N filters do suck some times, then the car dies, won't start, won't stay on for too long, and so on.

Dude, you really haven't met that many blondes have ya? 
Just teasin' ya, and no offense Bella.
Bella,
Welcome to the family!
Take Bill Curlees advice and check the wiring and connections. Clear your codes, and wait for it to happen again. If the sensor is truly bad, it will throw the code again right away. If it's a wiring issue it may take a while for it to happen, as the wires have to be put in such a way as they break contact and throw the code. Once contact is broken, the code is thrown. Then contact is re-established and all is well again. Maybe it only happens when you hit a lage enough hole in the road, or enough vibration causes the wiring to break contact.
Let us know what you find out on this.

No offense taken. As for the "dumb blonde needs help" comment, I first started a thread called something like "air intake sensor question" and only one person replyed and that took an entire day. I then reposted it with the dumb blonde remark, and see what happened! Not so dumb afterall.
After all I've read here, I'm inclined to believe that it is a bad wire. The check engine light will be on sometimes, I'll park the car and the next time I drive it, all is well. Does that sound like a wire problem to you?

If the problem comes and goes, and changing the sensor only works temporarily, it is probably a broken wire internally. Vibrations, and movement will allow it to contact, and then break contact the ends at the break point.
Once you learn to check codes, which is easy to do, it really helps you to figure out what is happening with the car.
Also, it's rather funny how your level of interest here increased when you announced that you are a blonde female.Work it girl!!

I used to own a '98 and am familiar with the IAT wires. That is not what I was referring to. The wires in the MAF are downstream from the air filter in the direct path of the airflow. If you over-oil any K&N type of filter the oil will travel with the airflow and contaminate the MAF wires and ruin the engine's operation. It's actually more common than you would think. The wires are extremely sensitive and can be damaged very easily trying to clean them.

you can pretty much gurantee that any thread title that references a female will get a lot of attention.

I had this problem before and it was the connector not the sensor
have a good mechanic check this for you

The check engine light came on so I went to AutoZone, they got the code and informed me that the air intake sensor was bad. I replaced it and everything was fine for about a week and it happened again. I went to a different parts place, they checked the code and gave me the same answer/part. Once again, it worked for about a week. I don't know if changing the intake had anything to do with it, I assumed that was the cause since I had just made the change. My car never ran bad or acted weird, if the check engine light wouldn't have come on, I would never have known anything was wrong. AC works great along with everything else.

I'd be willing to bet it is the connector or wires that plug into the IAT. Mine did the same thing as yours. Simply pull the IAT and measure the resistance and then take a hair dryer and blow across the IAT. If you see a change in the IAT you can be pretty sure it is the harness. I was getting the same results that you are getting. You can pick up the connector at your local Chevrolet parts counter pretty cheap. All you have to do is splice it in and reset your codes. I don't have the part # handy but I will get it for you if you need it.

Seriously doubt you had 3 bad sensors over a short period. Since each one works for about a week, sounds like unplugging and re-connecting the sensor makes it work for a few days. Therefore, I am betting the connector is working its way loose or a bad wire at the connector.
