hmmm, I would check everything in the area of your prior repair, could be your cold start injector maybe you knocked off a connection or something while working on it before. I knocked off a vacuum line once and my car would not run properly either, took me awhile but I found it and it was fine. If after you determine that everything is intact start with the common problems, like the fuel filter. Check to see if all your ignition wires are ok, you might have knocked some off or loosened them. Check them at the distributor as well. Another item to check is the connector to the temp sensor. Good luck!
