Thread: P0101 MAF...Replaced and still throwing code HELP!

Give your fuses a check. A 15a ignition fuse comes to mind. Other than that, maybe you just got a bad MAF? Try unplugging the MAF and then starting the car and see if it eventually smooths out. If it does, then turn the car off, plug the MAF back in and restart. If it runs like junk again then you probably have a bad MAF, which is possible for even a "new' one.

Thats just it...The car seems to run fine with the code. The only thing I notice is when getting into a heavy load or after about 5psi of boost it sputters. Other than that it idles and drives fine.

Is the MAP HG supposed to fluctuate? I just hooked up my scanner and it is showing a constant 28.1hg, when i drove it around the number only varied slightly and it went up IE 32hg. I thought it was supposed to read vacuum and boost. My boost gauge is working and even just sitting at idle if i give it gas it will go to 0 which i know it should but im not sure about what the live MAP sensor should be reading.
