o2 question

[cmokem]

Hi all

Just a quick question here.....what would make my 02 volts read 0.0 when I de-accelarate. I just noticed this recently and have changed out the 02 sensor and checked the grounds....all looks good. There are no codes that have been pulled either.

Thanks in Advance

Bob

When a fuel injected car deccels the computer shuts the fuel injectors off momentarily(SP). Check that you dont have exhaust leaks either.
