Low compression in a single cylinder, together with a misfire code (get the codes read) is a fairly reliable diagnostic for a burned exhaust valve. Usually on cylinder 2 or 3. If that is indeed what you have, then you are looking at two possible options if you want to keep the car: 1) a cylinder head overhaul, 2) replacing engine with a known good (guaranteed) used unit. The cylinder head work is about 15 hours labor and figure another $500 in parts/machining. The replacement engine route is about 18 hours labor and say $1000 for a lower mileage unit with guarantee from a place like Erie Vovo. If you are doing the work yourself, it is obviously cheaper, but it does not sound like you are doing the work. So if you budget $2,500 for the job, you won't be too far off.

Not sure if 105 was even avail. at the time. If so, I wasn't aware of it. Thus, I went with what I knew: 109.
