Hey, I got my vacuum lines all re-run last week, and ever since ive left the shop, my "service engine light" has been on.
Starting about a week ago my car has been sputtering whenever i start it up, it seems like its about to stall out whenever i hit the gas.
What are somethings i could check that would potentially cause this?

 

Well first off, you shouldn't have left the shop with the SES light on if it wasn't on before. Take it back and have them scan it(For Free) and find the problem.

 

Lets start with the code(s) that are present and go from there.

Could be his shop or an actual mechanic...
