will its been talked about 100 times but still havent found the problem my car idles from 3rpm to 2rpm then its slowly goes down i have a 93 dx sedan it does this alll the time even when i drive it and its all warm it still idle from 1 to 1.5 rpms i changed the iacv still nothing going to change the throttle body see if that work but what esle could it be

i search

 

Do you mean to say your idle is pulsing up and down all the time even after the car warms up? If so, replace your thermostat. Had that happen on my 94 and drove me nuts for 2 years before I figured out that the thermostat was stuck open.
