I have an issue with my car hesitating between 2000-3000 rpm when I gas it. If I accelerate quickly it doesn't do it. Also I have an engine light on as well (P0102). I know that its a MAF issue I tried working several issues changing the air cleaner, which is after market (cold air), cleaned out a small motor on the throttle body which was caked with nasty stuff, and it doesn't kick down properly sticks at 2000 for a second then to 1.5k for a second and 1000 for a bit longer then finally 700 idle.... Sorry so long and jumbled but I'm on a blackberry.... Just need some help.... TY! Oh and I recently changed the plugs and if you own one you know what the involves.

Have you tried putting a new MAF sensor on the intake itself? i have an '03 GT with a cold air intake and had a similar issue with both the engine light and rpm hesitation. I forget the code i was getting when i put it on the computer but it ended up being the sensor. Put a new one on last spring and that solved everything. Just a thought..

Thank you for the tip, I as thinking that and was trying to avoid it...lol, but I suppose that that might be the issue, every gear does it at that rpm as well, all the way to 5th. Thank you for the response, thank you very much.

No problem, let me know if that takes care of your problem. My sensor went bad, and my rpms were sticking the same exact way cuz the computer wasn't reading how much oxygen the engine was getting right away so it wasn't kicking down, or up at the right times, which gave me a hesitated response for the engine. But replacing the sensor is a easy enough fix, I hope thats all your problem is too man.

Yup! changed the MAF and the little red devil is running smooth again! BTW cost me $141.00 with a core included. I noticed on my old one that the little metal piece in there actually had 2 small cracks in it. Something made me check since if I purchase the part I can't return it.... but the part has been replaced and the car is running strong thank you again for the tip!! I love this place. Later all!

Hello. Just a suggestion to both of you next time the problem returns go to auto-zone and buy a 6 dollar can of mass air flow sensor cleaner its a lot cheaper and works 9 times out of 10. =P
