Car vibrates, runs really rich the Service Engine soon light comes on

[TYGRR]

Hey everyone,
Im having some trouble figuring out what is going on. I just got my car back from the trans/tuning shop and i got about 10 miles away and the car began to shake really bad as well as the CEL light came on. As soon as i turn the car off and back on the problem goes away and no shakes. however, the CEL stays on. I also can get an OBDII to communicate with my car. The motor has only 10 miles on it. Its brand new. What could possibly be causing this? Please help.

umm, besides that it could be a number of diferent things causing this, one could be a vacuum leak causing it to run so rich, or maybe u have a bad sensor thats causing all these problems, it would be dificult to tell with this info, what mods? how long was it sitting in the shop? check what code? the code is most likely related to emissions which by reading the code you will know where to look at from there!!! chk it out first
