I'm desperate for advice. A few weeks ago my check engine light started flashing while driving and I barely made it home. It was jerking and little power with a bad smell. Got it towed to a mechanic and after all was said and done they quoted me $3800. From what I've researched on here is an engine misfire and the mechanic verified that, but added on a ton of stuff... change all of the cylinder coils, spark plugs, timing belt and other things because of an oil leak, engine mounts and more. I guess my question is if it's worth getting any work done on it or should I just try to get it off my hands? I'm an unemployed student and really don't have the money to throw away.
