ok, i have a ls/vtec integra at my vocational school thats being really confusing, its idle fluctuates from 3000 down to1000 back to 3000 and so forth. i was pretty sure it was the iacv , but i put a different one in, and its still doing the same thing, then i checked for vaccum leaks with a smoke machine, it has none, i then bridged the obd1 plug to see if it would throw a code, my luck , it didnt. im completely puzzled, maybe someone can help.
