Car putt putts when engine gets hot..

[cedgtp24]

When the car is cold it runs good idles smooth, but when it gets hot it starts to putt putt putt and it shakes a little on acceleration until it gets over 2500 rpms. Has anyone here had this problem before? Im thinking the coil packs since the are so close to the exhaust manifolds, but when I pull the plug on the MAF sensor it idles up to about 1500 rpms and the putt putt goes away. Any thoughts on this? Thanks..

My Beretta used to do that. I replaced the fuel filter, the coil packs, plugs, wires, and finally the injectors. The problem went away, so I can only assume it was one or a combination of those things.
