car does not want to run right

[rgreen86]

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

did you change the fuel filter, if not you should change it, also check the ohms of the injectors should be 13.5-19 ohms

check everything over you might have a vacuum leak somewhere and check all the injectors again you might have another one that isn't plugged in right and unplug the battery for ten mins and plug it back it the computer might still think the injector is unplugged still.

Did you retrieve codes? A code be help with diagnostics (the CEL does not need to be on for a code to be stored in the KAM, and this kind of issue very well might NOT light off a CEL).

Good luck.
