Is Engine Misfiring?
 

I saw this posted here before but can not for the life of me find it. My car was running rather well on Friday, but it's been a while since I've done a tune up. Saturday I replaced the wires, plugs, cap and rotor. It started right up and it idles at about 700, but when I go to drive it when I hit about 4000 rpms it just drops back down to idle speed. Now I can't even get to the Auto Shop for the other stuff I need. Anyone knows what gives here?
