What internals did you change. Usually an ignitor causes bouncy idle.

check the main relay under the dash, it controls the fuel pump. the leads on it could possibly be cracked causing a bad connection and thus your jumping tach. I had mine replaced when i did my ignitor/dizzy/cap/rotor/wires/plugs.

check you injectors and pressure regulator too...they may have been damaged or dirt may have gotten in them during the swap...also check for vacuum leaks...
code #43 relates to the o2 sensor or fuel supply system...by the book you should check the following items in this order (this is based on what you have told us):
1. Fuel Injector
2. Injector Resistor
3. Pressure Regulator
4. Contaminated Fuel"I can imagine no more rewarding a career. And any man who may be asked in this century what he did to make his life worthwhile, I think I can respond with a good deal of pride and satisfaction: 'I served in the United States Navy." --President John F. Kennedy
