Symptoms are:
-High Idle at about 1300 RPMs all the time.
-Sometimes the cooling fan runs continuously even from a cold start.
-Sometimes the engine will sound like it is running off of two cylinders and have no power.
-Codes P0300, P0140, P0325
-Car ran good up until the battery died one day which caused the ECU to reset.

Things I've fixed/checked:
-O2 sensor (bad wiring)
-Knock sensor
-Ignition module
-Coil packs
-Coil towers
-Spark plug boots
-Spark plugs
-IAC motor
-TPS
Everything checks out good.

Is the ECU going into limp mode causing all of these symptoms? Should I just install a www.msefi.com like I did on my other car? Or just drive it to the scrap yard?

Thanks in advance,
A.J.
