I'm new here, and am blown away by the amount of info available. It's a great place. I have an 02 I35, and have never had a problem with it until:

2 months ago, my tcs, slip & check engine light lit up. Power was way low, at 2500 rpm, it would just drop. I go to my mechanic, and he says its the MAF. I ask why it would go out at 60k miles, he says they do that, no big deal. Charges me $500 b ucks for the part. ( I checked online and saw similar prices).

Now, today, starts again. I go to autozone and get code P1102. The computer says "MAF within range but less than expected". What does that mean? What could cause the MAF to keep going out? I'm going to the mechanic tomorrow am, and I expect him to fix it again free, just wondering if anyone knows of anything he may have done wrong or if this is some sort of known problem.

Thanks in advance.

There could be another reason your MAFs are getting damaged....the 5.5 gen MAFs are notoriously weak. Make doubly sure first that your intake assembly (stock or aftermarket?) is secured, make sure the MAF wiring is in good shape, MAF plug is clean and not grimy, etc. Vibrations and debris can hurt MAF performance....
