Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
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.Since the engine seams to be misfireing I would start with making sure there are no vacuum leaks as well as inspecting the spark plugs to make sure none are fouled from sitting so long. Im not finding any reference to the code Po46 which is an OBD 2 code and your 1993 should be an OBD I system, are you sure about the code?
Please do Rebecca, check for vacuum leaks as well as inspecting the spark plug to be sure they are not fouled from setting.
