Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Before you consider replacing the computer try disconnecting the negative battery cable and clear all the codes and then reconnect the cable and run the engine and see which codes reset and once you have them post back with all of them and I will advise from there.
