300E idles at 500rpm!! IS IT NORMAL???

Hello Board,
My 300E has been doing this for a while. The idle speed is at a dismal 500RPM!!!!. I at first thought that it was normal, my car sounds quiet,but it feels very underpowered during acceleration. I have cleaned out the idle control valve. What could be causing this??


I have replaced:
Cap and rotor
Plugs and wires
Air filter
Cleaned idle control valve
All vacuum lines
Fuel filter
Injector seals


What could it be??

ECU??
O2 sensor??
Fuel injectors??

HELP!!!
