Ok so here is my situation guys.... car runs smooth through the powerband until I reach about 4k then it begins to bog down and sputter a bit. I took the mas airflow sensor off and cleaned it reset the ecu by disconnecting the positive battery terminal and it was running fine but then began to bog randomly through the power band sounds like a faulty mas airflow right? I need some input on other possible things.... also on where to get a mass air sensor quickly. Thanks guys in advance.

How did you "clean" the MAF? PLEASE tell me you didn't rub it with a towel or anything. You are supposed to use "electronic contact cleaner", spray it on there and let it dry for like 30 minutes before reinstalling.

yea everything was closed thats what we were trying to find... no i didnt use a towel i used a tooth brush something that wouldnt leave any residue behind. You think some contact cleaner monday morning will definitely aleviate the issue?

Does it sputter only under WOT or all the time over 4k rpm?
What leads you to believe it's a maf problem?

ant350z

both during wide open throttle and gradual. Its not like clockwork or anything it kind of just a random bog... and the real reason we think its the MAF is because it seems like a computer issue because the car is going smooth and then it seems like a forced stop. .... I dont know that was just like mine and my friends logical deduction because its happened to us with other cars and cold air intakes.... what are other possibilities?

Change your plugs. Guessing the OEM plugs are still in the car.

Make sure the maf is pointing the correct direction as well.

Seems like it *could be a MAF, but I am unsure. A toothbrush is a bad idea as it has a good chance of scratched the surface of the MAF, fouling it completely. I would just wait until tomorrow and get some contact cleaner then before trying anything else.

Is there no Home Depot or Lowes around you?

ant350z

yea the oem plugs are still in the car. Also the MAF is on the car correctly. WHats a good plug to go with that you would suggest also can i get an MAF at any dealship and does anyone have any idea how much they cost?

Start w/ changing the plugs.
Just use the search function of the forum for the NGK part number. There has been quite a few threads about plugs.

Hopefully the MAF isn't damaged. Try the plugs, let us know how it turns out.

ant350z

will do... but any idea what a new MAF costs or if i can get them a dealership... ps thanks a lot for all the input. really appreciate it.

i don't see why you wouldn't be able to get them at a dealer... i imagine they are QUITE expensive. If I'm not mistaken, a MAF for a 4ag from toyota... that's right those old engines from the 80's, is about 200 bucks...

That right there is why people will tell you to fight the urge and not clean your MAF sensor. I wanted to really bad but didn't. LOL

They are around $500 from Nissan. I know of at least two that have gone bad but they were both on cars with FI.

ant350z

thanx a lot for the input guys... I'm going to be cleaning the maf with some contact cleaner and changing the plugs today and switching over to redline synthetics hopefully she will be running even better!

Do you run a pod filter? and if so is it a oil based one.

Sometimes the oil from the pod will contaminate the MAF and will cause you issues.

Typical problem on WRX's with pod filters
