ps374, You are correct, it is better to go slow and ask questions than to rush in and foul up things. If the car is substantially modified to the point you describe, you definitely should double check everything up front before taking action.
Sorry if I came across as harsh. You did mention earlier that the ECM setup was not stock, so maybe we all should have gone easier on you. Please remember that the readers of you posts do not usually know the extent of the differences between your vehicle and stock. It is always good to provide lots of background info on the vehicle when asking questions. It sounds like you have the right attitude to survive here at CF and resolve the current problems with your Vette. Bravo to you and Welcome.
As for tools for throbleshooting the Vette , you will need a 10 MegOhm Multi-meter. Preferably a multi-meter with the ability to measure voltages (AC & DC), and resistance (ohms).
After you install the new O2 sensor come back and let us know if it helped resolve the problem. Remember, after installing the new part, you need to disconnect power to the ECM to clear the existing codes and see it they are gone for good. The ECM will have to "relearn" some of the driving parameters of the car after being cleared. This is normal and is usually accomplished with a simple 15~40 minute drive.
There are 2 excellent reference books on the Chevrolet/Corvette EFI systems available for relatively cheap.
"How to Tune & Modify Chevrolet Fuel Injection" by Ben Watson, is in my opinion a superb starter book for the new EFI based Corvette owner. It is less that $20 retail at Barnes & Noble or even cheaper at Amazon.com. It will teach you all of the fundamentals and has some excellent troubleshooting sections.
"How to Understand, Service & Modify Corvette Fuel Injection" by Charles O. Probst, is an even better book, but I would recommend that someone new to fuel injected Vettes start with the Ben Watson book and step-up to the Charles Probst book. Probst's book is $35 retail at Barnes & Noble, and also available at Amazon.com. You could always buy both together and see which becomes you favorite. With those 2 books and the FSM, there should be almost nothing you cannot troubleshoot and repair on you Vette yourself.

Post #11 - RRT vette ... Disconnecting the battery will clear stored codes.
Post #14 - Mike_88Z51 ...You will need to disconnect the power to the ECM for 10 seconds to clear the codes in an 84 OBD1 and see if your troubleshooting has been successful.

I'm guessing that if he read and followed the advice that he asked for, he wouldn't have to re-ask. He says he has the FSM, but he refuses to read it and learn how his car works. I get into trouble for my blunt sarcasm, but it gets pretty frustrating when the person asking for help, won't help themselves. With some, I get the feeling they expect one of us to "drop by" and fix it for them.
