I am having trouble trying to figure out why my car is cutting out. It starts to misfire or cut out when I accelerate a lot. In neutral, or when I shift through the gears easily, it runs good. It is only when I put it in a bind so to speak. The check engine light does not come on and it idles good. The car has about 90,000 miles and is a 1998 gt with 4.6 liter V8. I have put new autolite platinum sparkplugs and a new fuel and air filter. I have also put new exhaust. It doesn't misfire at all when cruising. I will change my plug wires next, but I have a feeling that is not the problem either. Any ideas to what my problem may be would be greatly appreciated. Thanks.
