I have a 1992 Honda Accord EX and I just got it back from the shop to have a radiator hose replaced that was leaking, oil changed and air filter checked/replaced. The car is driving fine, but when I got home to back the car into my drive way, the car was really idling badly and car was actually jerking. What is the problem. I am taking the car back tomorrow...but any ideas what happened?

 

Ask them if they bled the air out of the system when they refilled the radiator. Air in the system will screw up the temperature sensor reading.

There is a bleeder valve that should be opened on the thermostat housing to allow air to escape when filling the radiator.
