97 Camaro P0102 Code

For a while now, my 97 Camaro 3800 series has had this P0102 code. Recently, I replaced 2 oxygen sensors, the ICM, the PCV valve, the fuel pump, and I did replace the MAF sensor in September. The car itself is running very poorly. It hesitates when its accelerating, most of the time it idles around 1500 RPMs (sometimes around 900-1000), or it just sits and sputters between about 1200 and 800 RPMs. Its also died a couple times when i've just been braked at a light. What else could be the problem? Should I check for vacuum leaks maybe? If i can't figure it out I may just take it to Chevrolet and have them diagnose the problem cause I hate putting so much money into it...

Sounds like you have been just throwing parts at it...
Start by checking connections to the MAF, or it could be the MAF its self. Another possibility is that the ENG fuse is bad.

P0102 Mass Air Flow (MAF) sensor circuit low frequency

It's MAF related.
Wiring issue maybe?

Won't really work, the MAFs are digital not analog.

More I think about it he needs to check the engine sensor fuse.
Blown engine sensor fuse will set a P0102.
They get blown when the wires to the heated O2 sensors get shorted out.

replace the MAF simple as that! I have this issues with a 3.8 maf and the 5 speed car surges and buck, the auto car hesitates but when it is replaced in either car with a good one cars run fine.

The two O2 sensors were from another code(s) actually but yeah i've just been checking and replacing parts that apparently are related to this haha and i did take the ICM to autozone and they said it was bad

The only thing related to a P0102 code is the MAF. Period
Changing other parts won't fix it.

Alright I'm back....... While there are no engine codes it's still kind of sputtering while accelerating. The battery is pretty much gone and I had to jump start it, I doubt it could cause something like that though. (Will get a new one tomorrow) I had the MAF wiring corrected and fuel injectors cleaned so I'm kind of clueless as to what it could be now..

You would be surprised as to what a battery will cause when its on its last leg, especially on a vehicle with a lot of electrical. Believe it or not, I had a 3800 series Buick come in one time, sputtering and kicking a little bit but wasn't throwing a code for some reason, tested the battery before parking it for the night...you guessed it...bad battery. I changed it with one I had sitting on a shelf and sure as hell, ran just fine...drove it 51 miles and no codes popped up. You might wanna make sure your alternator is in good shape while you're at it just to be safe.
