Default 98 7.4 454 Running Rough

It threw a map sensor code and it will run smooth, then start running rough and cut in and out badly going down the highway. I replaced the MAP sensor twice and it is still doing the same thing and keeping the light on. Code is p0107-MAP sensor. Any help would be greatly apprichated. Thanks!
