Hi, I have a problem with my civic, when its get warm the idle doesn't work correctly its goes from normal to under 1RPM then get back to normal then goes again under 1rpm all the time any help will be apreciated.

What I was told and think is TPS Sensor is dying.

Thanks in advance.

My 2000 civic had the same problem and replacing the tps took care of it

If it is going up and down you could have a couple of things wrong. Vacuum leak, idle bypass screw out too far or bad fast idle valve. Fast idle valve can be checked by removing two screws from top plate and checking for vacuum leaking. It should be sealed at normal operating temp.
