My 1993 Subaru Legacy is idiling rough and bogs down when you try to give it gas (it will rev up if you butterfly the gas pedal). If you put it in gear, it wants to die and will not rev up at all). It has an EJ 22 (2.2 liter) non-turbo engine with 160k miles. We have replaced the TPS, MAF, IAC, coil, plugs, wires, ECM, fuel pump, and knock sensor. This didn't change anything. The components came off of a running 93 Legacy with no codes. Now we are getting codes for the knock sensor, MAF, TPS, and Air Control Valve. Is there a common electrical connection that could be causing our trouble or is there anything else that we might be overlooking? Any help is greatly appreciated! Thanks, Dean
