Can you help me

[godsention]

my 99 3.0 has recently been overheating and now its misfiring I replaced the plugs and wires and and coil pack it still is misfiring, I had it diagnosed with the check eng light on they said it was a misfire, but What else should I replace/check Please Help!! it is not real sluggish until it gets to about 50 or when I leave from a dead stop and while stopped it feels as though it wants to die

Overheating can depending on the severity warp the heads and you can even get blown head gaskets. Check all your fluid levels and fluids for contamination. check your plugs for abnormalities and do a compression check.

Yep, check the engine oil fer coolant and check the coolant fer engine oil, also, could have a compression leak between cylinders.
