Gas milageguys, down..down..down the drain..?

[hudsongua]

Hi Guys,

My gas milage went don the drain along with my acceleration..My 95 E420 does not respond fast to kickdowns and accelerates either sluggish or slow depending on how I step on the gas pedal, (hard and fast = slow start, slow and steady = even but slow acceleration, not terribly slow but not good either). One the car is rolling high speeds are not an issue, its just getting to them from a dead stop..However no matter how smooth I try to run it the car is swallowing the gas like nothing..about 12mpg..

I have new OEM caps/rotors, spark plugs and wires and no vacuum leaks..

I got a KS code a long time ago but has not returned since I cleared them 2 months ago..No CEL light on as well..Could this be the EGR, MAF, O2 sensor Throttle actuator or the KS that went kaput but still haven't turned the CEL light on..??

Any help appreciated..this LOW milage is not fun at all..

THxz,

DH
