Maf is bad again

I put my new MAF in last week and its already bad. I find it real hard to believe the Super charger caused the MAF to go bad in a week. Im having cold start issues again so today for fun I unplug the MAF and the car starts right up, pulls proper vacuum and idles perfect. Plug it back in and the car will hardly run. It would be easy to blame the SC unit but when the car is cold its obviously not producing boost and for the most part spends most of the time in a state of vacuum. Im going to call the parts supplier on Tuesday and see what they have to say. Its probably going to go something like this "Sorry there is no return on electrical parts." Im still going to give it a try. Spent alot of money on parts at this place, we will see.

Try clean it a little first, maybe you accidently dirtied it when you put it in, not implying anything though

Im afraid to do that just in case the parts place decides they will take it back. I dont want them to say I damaged it.

Do you have a stock intake? I ask because if you have an oil-based aftermarket air filter like a K&N, the increased air being pulled in by the SC kit may be pulling oil droplets into the MAF and fouling it out.

I avoid the K&N type filters and actually put a new factory air filter in when I did the MAF.

Well, if the MAF still under warranty you can still go to the place where you bought it

They're return policy states that they do not accept returns on Mass air flow sensors or anything electrical.

Then go ahead and clean it. A MAF cleaner may only be 10 bucks, I have heard other stuff works too.

I was worried for nothing, they gave me a return authorization number. No big deal just have to send it back.

i would put a K&N anyway, just remove the oils prior to installing, I did that and have yet to have an issue with it. MAS is good and sound and pick up is great....No different than using those $300+ cone filter intakes since they dont use oil either. Probably the vacum pressure in the intake and the restrictive flow of the stock filter is causing this.

If the intake tube is plastic, it could be flexing during full boost on the vacum end of the intake tube.
