Help! I have a 1993 Honda accord. 4 cyl. 16 valve... I have oil in all 4 plugs. I not talking about a little either, There is a good amount. I did put new spark plugs in She is running, but is not very happy about doing so. The shaking is like high speed on a washer and the shaking seems to subside some as i get to about 50 mph. what is wrong with her? Why is this happening? Did I do something to her that would have made this happen? I very worried. She my only car. Please help!!! Thank you so much, Karrie
