Cleared the codes to get home and it ran great for the week it took for my new MAF to come in. When it came in I replaced it and not a week later it happened again. Actually seems to happen every few days. Same code, MAF B. Got new air filters, and same deal.
I did not do the relearn process, do you think thats my issue? I have resigned to just clearing it once in a while but its a PITA as it has left me on the side of the road several times in bad places.

mxquattro,
Did you by Infiniti MAF senor or so called OEM parts? I am thinking I should have spent the +400 for the two Infiniti parts and not the RockAuto ones even though they appear to be the same ones I had that "failed". OH and I did jinx it because the SES (Service Engine Soon) light came on at 650 miles. I did the full Monty relearn but it came back on after 150 miles. About to call uncle and bring it to my service guy ( not Infiniti but really good ) and let him have a go at it. LAST result is dealership.

I did, I got the exact same one as you did from Rock auto. I did the full relearn procedure and this weekend it did it again Killing me! Im thinking maybe I just need to pull the battery terminal off for a while and then try again, I think that relearns the ECU too. I brought it to the dealer and they say it could be 'several hours' of troubleshooting, and may find nothing. That equates to about $350 which may come up with nothing. Funny thing is, I NEVER get a CEL or service engine soon light. nothing. No lights at all. I just cant go over 2500rpm.
Im literally ready to sell the car over it.
Please keep me informed on what you find!
Did you pull the codes from the flashing SES?davidcosmejr wrote:My symptoms sound similar, except that I do get the SES light coming on eventually. I learned how to get the light to turn off. When I did that the car soared past 2500RPM with no problems. The light came back on. I reset it again after putting in new air filters. I haven't drive much since then. My question is for those who had the SES light come on. Did you try resetting the light, and if so, what was the result?

I just bought this car about 2 weeks ago from an Infiniti dealership! Unfortunately, it was As Is. Ugh! Any suggestions?
