14 gt p0100

I have the P0100 code. Bama tune, boss intake, LT's, high flow bbk x pipe. I've driven it like this for a while, but it stalls out at lights and hesitates at certain times.

A while back, a shop found that the wires coming off of the MAF wiring were chafing because my JLT intake was pushing those wires against something. They fixed those wires and I was good to go.

My car runs freakishly rich, fills my garage up with eye burning fumes and makes my smoke detectors in my house go off.

I've looked at the wires that the shop fixed, they have no signs of wear, they all look intact. I replaced the maf with a brand new one and still have the code. I have also changed out both 02 sensors at the same time.

the p0100 code is still present after all of this. I erase the code after each time I replace a part but the code comes right back. The closest tuner is a 6 hour drive so its not that easy.

Does anyone have experience with this issue that can shed some light? A diagram of this circuit would help me out the most.
Thanks everyone

Error Code P0100: Mass Air Flow (MAF) Circuit Malfunction. Error Code P0100 is described as a Mass Airflow (MAF) Circuit Malfunction, which basically refers to a problem in the electrical circuit between the MAF sensor and the PCM (powertrain control module, also known as ECM or electronic control module).

If I can find a diagram of the electrical circuit between the MAF sensor and the PCM, that would greatly help. I can not seem to find it anywhere. I am trying to understand what other components are on this circuit if any. Thanks

sorry I can't help with the wiring diagram . . .

but it is probably something simple like the connector; I think I saw some other post on here about some goofy problem with the MAF connector, like one of the wires comes out or something like that

Why, do they go bad over time? I didn't realize that tunes had a limited shelf life, LOL . . .

But seriously -- did the code start when you got the Bama tune; or did it run fine with the tune for a while?

My gut is also get rid of the tune. But chasing down any potential MAF issues before you do that seems to be the next logical step. If you chase it down the line and end up with the tune being the next thing to look at, consider data logging and sending info off to one of the reputable "remote tuners". I know it's not cheap, but it may get the car fixed if nothing else rectifies the problem before that.

I had purchased a cheap autozone MAF and installed it with the same results. Today the C&L MAF came, I swapped out the Autozone MAF and the code was still there. I wanted to do that first in case the C&L MAF fixed the issue in order to know what the issue was. I returned the car to stock, fired it up and looked for the code and it was not present for the five minutes that it was running. I have a steeda tune for my car, I will load that up and see if the code comes back.

I have heard great things about the other mail order tunes. For me, I don't really like steeda tunes because of how the throttle is, not a big deal and not bashing them, just preference. I would be inclined to lean toward Lund tunes. What is the consensus out there?

What's funny is that I can not say that one day the car started acting crazy. It happened over the course of a year or so.

Then it probably isn't the tune, because they don't change over time. It has to be something else, like a connection getting loose or a wire wearing out of a sensor getting dirty or something like that.

My car continually stalled with a Bama tune and a CAI, was fouling O2 sensors and generally had poor driveability problems that got worse over time. I would go with a better tuner from someone like Lund or AED then see what the data logs say. There is no one and I do mean no one that would recommend Bama with his mods. My car runs smoother now than it ever did stock with just a Bama tune.

hmmmm, trying to think of how a tune-related issue could get worse over time . . . I guess if the tune was rich, then things could get fouled and that could build up and get worse over time; but I can't see how it could be fine after installing the tune, and then change later; unless something else is changing

datalogging sounds like a good idea regardless

Update---
Been on the phone with Bama getting help.

I installed my factory airbox with factory MAF and with a revised tune from them, I had no MAF Codes pop up.

It was a step in the correct direction.

Called back, they sent out a revised tune for my JLT cai and I now have the P1101 code. They are out for the day, I will continue
moving forward tomorrow.

As I said, dump Bama. If you do not believe me, do a search.
