i have a 95 mustang gt. when i am driving my car and hit 3500-4000 rpms my car starts to hesitate. i had this problem when i first got it and it went a way when i replace the coil, plug wires, plugs, distibuter cap and rotor. i just recently replaced valve cover but when i put intake and others back on it started again. i drove it for about an hour and i noticed it had no power when i gave it any gas. i looked the engine over and i accicdently unplugged a fuel injector. i plugged it in and it still has a hesitation at high rpms.
thanks
