Opened hood to add wiper fluids noticed engine was shaking a bit much! Don't know if it's normal or something to do with motor mounts but only while I'm sitting at the red light can I feel the car shaking.. I'm still at 650 rpm while sittin n no major difference in driving! I did recently do a spark plug n boot change noticed a vacuum line kept easily coming off the 3way connector ,but i taped it up pretty good to ensure Air wouldn't get thru! Any ideas or suggestions??

It's not normal. It should be dead smooth. Might want to double check your work. Maybe a coil contact spring not seated properly causing a misfire?

Awwww shucks I'll check it out! Thx

I just checked my codes and p0300 is my history, not current! I did forget to mention that I did add a quart of oil because I was low until I can do a complete oil change this weekend! I just looked under the hood in it was a very very slight shake! Nowhere near like two days ago!
