    Free Scan\low res pulse code

    I have a free scan if anyone has the time could I e-mail it to you and you take a look at it I'll put it in a excel format.

    Also I hooked my car up to my computer today to try to get an idea of my ongoing stuttering problem. I waited till it was in closed loop and took it for a short drive it stumbled and missed the entire way. As I drove back to come up the driveway the car died and would not restart. I had to tow it up and when I looked at codes code 16 low res pulse came up. This is the opti right? I just replaced my opti and the code was not there before I drove it today could something else set the code?

    A corroded OPTI connector will do the same thing. Mine had to replaced twice.

      E-mail me your log in Excel format.

      DTC 16 is "fatal" if its an active code. When the PCM doesn't "see" the low res pulse pattern from the Opti, it shuts down the fuel pump and injectors.
