I got a 95 model SE 24valve v6,with a 5 speed the car idles smooth, but when accelerating it stutters till you hit about 3000 r.p.m. then it smooths out, it only does this once you get it past about quarter throttle( does fine puttin around in traffic) .also it quits makin all that monsterous power at about 4700 rpm , is that normal? i thought that these motors pulled harder the farther they wound up .
