Just because you own an ECLIPSE RS(Not a dsm) since you have first started driving(which means you're still probably under 20) and it's probably your only car experience you have had your whole life doesnt mean you know how to deal with them. So like I said before, why don't you try taking it to a mechanic who actually knows what they are doing.

*edit* I don't mean to come off as a dick but that would be the right thing to do, but then again what do I know.
