Blinking Check Engine Light and Severe Shaking While Driving
Phew.. Need help again, I have recently replaced the Engine and Tranny mount and now all of a sudden, my car drives very rough and shaking very bad and from time to time the check engine light will blink. Can this be misfire due to spark plugs? I have 120k miles and I haven't changed the spark plugs yet. 
Update:
Just read the fault codes: P0629 and P0633, anyone has any experience with these fault codes? From searching the websites it seem to indicate fuel pump, however a German site mentioned something about misfire P0629 and Combustion P0633. Can anyone help?

I can be wrong, but will fuel pump cause that kind of shaking motion while driving along with check engine lights blinking? btw, after I shut off the engine and so far I could not duplicate the problem again. Any thoughts?
