Sounds like its running rich. First remove an inspect the new plugs for fowling. An engine with a fowling problem will run great until they fowl up again, If the pugs look good try a can of "seafoam: additive to the gas first before you start spending money for diagnostics etc.The MAF sensor monitors air at cold idle. when warmed up it sends data to the engine computer which changes the fuel mixture ratio of gas to air which too can cause this problem.

Thanks for the reply, I installed a new set of wires, and it is running perfect again!
