Sebring Question

I have a 2005 Chrysler Sebring Convertible w/ 3.0L V6 and approx 60,000 Miles. I recently had my cooling system flushed, both radiator hoses, and thermostat replaced. The engine normally idled at about 800 RPM, but it is now idling at close to 1100, and it is running hotter than normal. I also have a hard starting issue. When I got in, I would normally be able to bump the starter, and the engine would turn over. Now, I have to crank the starter to get the same results. Was there anything done, whether intentional or not, during the service that would have created this problem?
