Sorry Kylar if one cylinder is down to 30 psi you either have to look inside the engine to locate the problem, or get a replacement engine.

Not running rough slight miss at idle

check plug gap .try a little hotter fire plug. sometimes the seals around the valve cover will let oil in around the spark plug causing it to misfire. as the 4 cyl engine has a coil pack and you cant see it till you remove it.
