    If you could list what trouble codes were present the first time you took it in, and the codes now, that would be a big help.
    How many miles do you have on your Navigator?
    Did they say why the oil pressure light and stalling problem occurred?
    I wouldn't have any work performed yet, there is something not right here. Definitely do not have the fuel injection service performed or the"tune-up", they need to address the problem you first came to them for.
    Let me know the answers to the above questions and we'll go from there.

    Have them give you the codes over the phone, ask for the OBD 2 codes. The codes will look like this: P0440, P0300 etc. Ask for the codes when you first came in, and the codes present now.

    Demand that they address the problem before any tune up, or maintenance is performed.

    Was the check engine light flashing?

    When the spilled coolant on the engine, how did they clean it off? With high pressure air or water?
