    sh*tty
    So, my$.02
    refund, eh? take the money and run.
    next, find a mechanic that knows WTF he's doing and get a second opinion.
    You may or may not have big engine problems. With a refund in your pocket you can take the time for a proper diagnosis and shop for a motor if needed.

    You never got a code for misfire or anything?
    How low is low?
    Like Ross said take the $$$.
    You may find the rings on cyl 5 just need to be soaked to free them up.
