Okay so my girlfriend bought a 2002 Jeep liberty from a dealership back in March. Last week it wouldn't start. After I replaced the spark plugs it started but was idling poorly. I decided to have it towed to a shop. They did a compression test and cylinder 2 has 0 compression. They pretty much told me I was probably going to need a new motor. I'm gonna have it towed back here so I can work on it myself. Is there any chance of saving it? I already have a $300 shop bill for the little bit of testing that they did.
