Engine Flutters under Hard Acceleration

This is a 2002 3800 V6 base model Camaro. It developed a dead miss and the Check Engine light came on. My son disconnected the Neg. battery cable for a minute or so but light came back on and miss was still there. I put the Diagnostic Reader on it and it showed #5 misfire. I replaced the plugs and the miss went away and light is not coming back on. Now it runs fine, but when you accelerate hard the engine flutters or misses until you let up a little. The CE light blinks while it is fluttering. Any ideas appreciated.

What brand plugs did you put in, and are they gapped the correct amount? Sure you didn't drop a plug which could have closed the gap? Or maybe cracked the porcelain on one when installing? Those things can happen considering the tight quarters to work in.

Car has 55000 on it, plug wires are origional and new plugs are AC 41-101. Gap is .060 on all and no cracks. At $7 a piece I used kid gloves. Will reset computer today like a mechanic told me to and we'll see what happens.

you may have to get a shop to put it on a dianostic machine to see what its doing while running. either that or pick up an adld cable and download a tuner program, i would suspect a coil or wires is going but thats a guess.
