Hi Brandon,

There are a couple defs for the codes you provided. Here they are.

DTC - 43 Electronic Spark Control (ESC) Circuit
DTC - 43 Knock sensor error
DTC - 53 System voltage too high
DTC - 53 Digital EGR Valve solenoid 1 error

So, if you will give a detailed description of you problem we can go from there.

Sorry for delay in getting back with you.

When was your last tune up?

If it is running rough then it could just be that it needs a tune up. With the OBD1 Systems it doesn't give or register a misfire or multiple misfires.
