Please help! 2-3 weeks ago I hit a pot hole, right after I hit it, it started shaking real bad and wont stop. Now every time I start the car it shakes real bad and it sounds like if its hissing and the check engine light came on. I don't know anything about mechanics but was told it may just need a tune-up, but am scared that if its been this long and hasn't stopped and I haven't taken it to get checked, because financially I haven't been able to, that it may become a big engine problem and wont be able to afford such a major repair. Please help!

You have probably jarred something loose. The check engine light is telling you what. If a vacuum line or something came loose you will need to put it back on. If you cannot aford for a real Mechanic to check it, bring it to Autozone a the will scan it for Free. However this may not give you the answer you need as codes can mean several things but it is a start. Depending on what is wrong, you could be setting yourself up for major problems. You can pay a little bit now or a whole lot later on.

Sounds like a vacuum leak and with all the vacuum lines located in and around the engine compartment it could be any one of them, Need to have a tech listen and troubleshoot what is hissing http://repairpal.com/directory?address=76110&car_brand_names=Lincoln
