ok i kno this is completly the wrong forum to be asking this but my sister had a 92 mucury capri non-turbo. it sat for two years cause the trans went out, after we got it fixed we started her up for the first time in two years. it was REALLY rough. After that i replace the fuel filter, rotor button, plugs(not wires yet) and a new air filter. but its still running like pure shit, almost like its on 3 cylinders but i kno for a fact it aint. If anyone can help it would be greatly appreciated. thanks in advance.
Oh and the engine dont smoke. except for the condesation smoke early in the morning.

yea all the fluids were changed including the coolant with 50/50. I actually rode it it today and when it gets up and going its fine but at idle it sits at 500rpm. and thats when the vibration begins:shrug:

x2, and have you checked compression?

You probably ought to just take it out and tear the shit out of it for a few miles, redline through the gears. That will clear it's throat a little, and if you get it good and hot it should help clear out any moisture in the case. Of course, this post is two weeks old, so maybe you already did that?

Is there a way to check for service codes?

If you haven't changed the gas, then that is definitely where to start.
