what is the tps. this is my first fuel injected car, so all these abreviations are doing my head in, i know what maf, pcv and cts are but what about IAV.???? i haven't tried the throttle control sensor yet as i've been trying to get it on the road which happened friday, so will this week. a new electronic idle control sensor is about 180 from nissan but i will try a second hand on from alljap or somethingfirst i think.just annoying.the lowest mine will idle once warm has been about 1700 or so. but usually about 2000, sometime 2500.
i am using the stock tacho!!!! how would i adjust the throttle sensor..... if u mean the actuator off the cable on the side of the inlet manifold then its fine, there is a few mil slack and seems to be ok. before it warms up it idle rough and cold and wants to die but after a minute or two its ok about 1500... as it get warmer it idles higher and higher

i had some trouble with my idle on my ca. was cutting out when i was pulling up at lights. got heaps of different advice but in the end found it easy to take it to a tuner and get it looked at. didnt want to risk it. playing with it myself only made it worse.
