Why is my check engine light on
I have a 98 acura integra with a Honda motor. I just changed the thermostat and the gasket for it. The car was running fine yesterday. It started smoking out white smoke from the radiator found out the thermostat was bad so I changed it. And I started the car afterwards and it's idling hard and reving itself up to 3K by its self no pushing of the gas pedal and it's smoking white smoke again from places. I also replaced the upper radiator hose this morning due to dry rot. And I also replaced the intake gasket this week too. I just bought his car and was told it had a few problems. And I've fixed those which was the exhaust and the cv Axel on the passenger side. what could be the problem?
