All was fine before the Thermostat was replaced.
Yes, I searched for vaccum leaks/pulled hoses and triple checked for any wires that may have been disconnected/left loose on accident and didn't find anything. I have not re-checked the codes and will do that tonight. we are talking about a small area and not much accidental stuff to do(i would think), but i will go back and check all these things again just to make sure.

As for the plug wires there was one that popped loose from the coil pack when i removed it and thinking that may have some thing to do with it I did reseat all the plug wires thinking that maybe something wasn't making a good connection, I will check those again also. Although the car does not lack power at all and drives fine on the road, it will surge idle very hard at a stop when in gear and idle rough when in park.

Thanks for the help, I will get back on the status of what I find in case you guys are interested.
