You're taking the right steps, double checking everything you did. If the car ran fine before & now doesn't it would seem to be in the area you worked. No SES or codes pretty much tell you all the sensors are plugged in & no wires are pinched (I'm assuming you have a SES light on with the key on engine off).
With the no SES now you are looking at mechanical, fuel, air. stuff not computer controlled. If you drove it far enough you would probably get a rich bank, lean bank, cat code, etc. But you don't want to do that.
After you've triple checked your work, I would start looking at the basics. Pull the brk booster line off while it's running, if it idles up & runs better it's getting to much gas. Put a vacuum gauge on it & check your vacuum. If its low & shaky, it's possible your T belt jumped a tooth. After its warm if the vacuum is slightly low & steady @ idle & drops to almost nothing under load you might have a restricted exhaust. You could pop an O2 out when it's bogging & see if that helps...
I still think it's is something you are overlooking when you put it back together but it sure wouldn't be the 1st time something else on a car failed right after a repair was preformed correctly..... BTDT
