MAF plugged in car sputter and spits......

[Cypress_h]

i've hit a brick wall here in my thoughts guys....
My car while it has been running great has left me scratching my head..... here's the story.

Car runs fine this morning get to work its still running great, go out at lunch fire it up its still running great go to pull out of my spot and it starts sputtering like no other. Limp it back to work and my guys at work tell me that the maf might be wet. fine, so i unplug my maf pull it out and its dry as a bone. but just to be safe i let it sit the rest of the day inside. go out after work hook everything back up and she's doing the same thing. now here's the best part, i unplug the maf and the cars running like its supposed to, no sputtering nothing abnormal about driving it...... im at wits end here. if you have any advice or can shed some light on the situation it would be greatly appreciated.

Your mas sensor is bad. Id upgrade to a 2g mas flows much more air.

i dnot know about the 2G MaF but you do need a new MAF, if you can get your hands on a scanner look At you BARO and get back with us

Check your ECU. Is your cel on?

cel light is on when i run the car without the maf plugged in like it's supposed to, no codes are thrown when its plugged in.

Also have the same case, was running excellent then suddenly yesterday when i pressed the gas it sputters and hesitaes at a certain rpm. i pulled out the MAF and the engine goes stabe but a little sputter at mid-rpm. Also my boost gauge wont go 1 Bar just like days ago. Already checked another maf and installed it but the problem is still there. boost leak tested also and it doesn't have leaks. tried to pull the gas cable, i notice that there's a certain rpm where the engine sputters, its at 4k - 5k rpm. Hope you can help me with this Thanks!
