When I first start my 04 Lincoln ls V6 is the morning the whole car shakes. Didnt really think much about it but it seems to be getting worse. No check engine light is on and after it is fully warmed up it seems to start. It will not do it for the rest of the day but it will the next morning. Any ideas on what to check out first. Any input would be appreciated and thanks in advance. Seems like when I fix one thing something else starts to act up.
