Got it while on the bottle . Mass Air Flow Sensor Circuit High Frequency P0103

I cleared it and it has not come back. What does it mean?

 

Have you ever had the reflash done for your PCM? I had that code keep coming at WOT shifts and the reflash made it never come back. It's some problem with the factory 98 PCM program.

 

Yes, I used to get that stupid code after I started running nitrous on the stock motor. It would come on when I shifted at WOT. I'm pretty sure it means you are pegging the MAF limits temporarily, or so it seems. I had that code deleted from my PCM because it was so annoying.

So its nothing to worry about? I have autotap so I can clear it when it occurs. I did not have the problem wihen I was runnig a 75 shot .. Bit now with the 100 shot it has come up.
