Did your repairs clear the codes it was throwing? If it did, are there any new ones showing up? Check your work to make sure you did not leave a vacuum line off or a sensor lead unplugged. Another thing to consider is whether your cat converter is not plugged. Hope this helps.
What code was it. What did you discover when you researched what the code means? Scan it again as has been suggested.
