Hard and fast = slow start.
Slow and steady = even but slow acceleration, not terribly slow but not good either).
Once 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 12 mpg..
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..
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 mileage is not fun at all..
THxz,
DH

That makes me suspect:
* A plugged catalytic converter.
* One of the two fuel pumps is failing or dead.
