Hi, I just bought my 91 SE 5spd, and I noticed a weird phenomenon. Even though the TB was thouroughly cleaned at the dealership, when the car is in neutral, at rest, I notice the RPM's begin to slowly rise and fall from 750 to 500. Now, this wouldn't really bother me except for the fact that when it hits 500 you can feel it, as if the engine is struggling to keep running for just a second. Remember it's a VG, not a VE. Any suggestions?

'bout same suggestions as on VG, maybe more & more expensive packages...

- complicator connections - sparklings - tps -

What does that mean?

1. Computer is the evil thing that complicates all the human life =complicator. Maximas have stacks of those.

Complicator is the source for misery in VG&VE &whatever 'modern' -used- car. Their idiotic input signal levels to be more specific.

2. sparks: the VGE has problesms in cap, wires, rotor. VE has those expensive cracking 'carrots'.

3. tps is tps... --->http://www.cardomain.com/memberpage/748507/6

Hopefully I clarified all?

idle air control valve most likely is bad try cleaning it out or go to a junk yard and pick up another one

My question is how do you keep them wheels so clean? That white on black contrast seems like it would show brake dust even if you tapped the brakes not moving.

I have the same problem, but it hasn't happened for 3 months up until a few days ago, i loosened the IACV screw to lift the revs up a bit so it wouldn't die. A mechanic suggested the IACV is bad and gave it a hard tap with the end of a screwdriver and the revs bounced back up to normal, it happened again today and i gave it wack with me phillips but it didn't fix it nor did several more hits (it's funny how mechanics do things like that) .
so i played around for a while and pushing the wire more into the IACV fluctuated the revs a little,,, anyway i think its stuffed and i'll get a new one,
but i might open it up and try cleaning the wiring harness first, will let u know if it solves the prob.

A question to anyone that can answer:
when the revs are at "normal" i think the revs are too high (around 1500rpm in P and N, and around 1000rpm in Drive) a tune-up will fix this right? cause i've taken it in for a tune-up and its still the same, also since i got a new tranny and i'm hell paranoid about it is it bad for it? because at a stop its making a wierd humming noise.
Thanks for any help guys.

When all is ok, the warm idle is flat 900 at N or P.

Clean IACV assy; might have soot or is leaking. Nissan FSM warns nissan mechanics NOT to open it... I cleaned, no leaks. Used some liquid seal on the last paper gasket.

can someone shoot a pic and point out where IACV is? Or at least describe its location on the VG engine? We aren't talking about the throttle body, are we?

Did you look at the post right above yours? He has a really good pic of it, should be pretty easy to see where it's at

Eric95se

that is a great writeup, except he does not say how to clean it!

Cleaning rag mastership is the treshold -level. Note: dont open IACV if cannot use, job ends in towing to stealership...

Rag utilization: some solvent might help, cleaner sprays, gas, alcohol or...?
