Engine Mechanical problem
2000 Cadillac Catera 6 cyl Two Wheel Drive Automatic 115000 miles

2 days ago I found that when I start my car whether in the am or after work, it starts rough for about 2 minutes. After that time frame it runs normally. I just changed the battery before the problem started and the check engine light is on.
Thanks for your help

check you fuel pump and filters... i had that problem with my Catera and had to replace the in line pump.... works like a charm now.. no more rough starts

Go to an Auto Zone, O'Rileys have codes read then post will advise.
