Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If you stall setting the same code and your sure the New MAF is okay and its the correct one then you may be dealing with a wiring concern to it affecting the signal. I would also make sure there are no unmetered air leaks in the air intake hose . See the steps to check the signal in the link below, copy and paste the link to your browser to open and view them.https://dl.dropboxusercontent.com/u/104923897/Code%20121%20Oct%2011.pdf
Unfortunately I have no control over the wait time, I work off the west coast so I'm sorry for the delay. The main thing is it sounds like you got it resolved . Thank you just the same.
