1996 Honda Civic Question: Idle goes up and down
Just replaced my radiator and my car wont idle. It goes up and down between 1000 and 2000 rpms. I tried to bleed the air out of the cooling system per recommendations from friends and some forums and engine continues to rev up and down. I checked for leaks in vacuum hoses and found nothing. What else could it be? Engine ran fine before I replaced the radiator for the 3 years that I have had the car. - koolout7
The engine idle speed will race up and down on a Honda if the coolant level is low or air is trapped in the cooling system, I suspect that is all that is wrong if the idle speed was OK prior to the radiator was replaced. - patrick mannion
Check to see that your ECT sensor is connected its the bigger sensor on the thermostat housing. then check your iac( proceedures for all this can be accesed by buying a Haynes repair manual for your honda). - ge.ezy
And also when im in gear and turning to the right it makes a clacking sound... whats wrong with it
Changed plugs and wires, value cover gasket and gromites. No cil. No water in oil.cil light goes on and off .When the cil is on when I turn the car off it goes out and stays off for awhile
I changed out the fuel filter, but the engine will surge up and down when at idle. at times almost feeling like it is gonna die but not accelerating more than about 1500 rpm. Would this be a vaccum...
Makes a circular kind of motion with vibration with speeds 72-74mph . Can drive some days forever with no light other days it stays on long time until shut car off. Once had a hard time taking off ...
engine is goiung bad, trying to get all out of its life. need temporary fix.
