i just cleaned my iacv and it got a lil better but my rpms still jump for 0-6,500 rpms just for the **** of it. now my cause idles at about 1,000 what can it be then gesh what a junk i got wtf!!

 

bump!!

 

did u try cleaning the throttle body and changing the fuel filter? .....and if your car drops from 0-6,500, youve got some serious issues.....i hope you mean 650.....well if its when your slowing down, and your car drops down below 500 and jumps back up, definately TB cleaning

 

Nooo just the needle itself jumps around from what I can hear my idle sounds normal, so bascially the gauge is going up and down and not showing what my actual RPM is and only happens when im driving not in neutrul/idle.

 

does it happen when your driving, and your slowing down to a stop? like youll be driving, say your coming to a red light....and itll drop under 500 rpm to about 250, then itll jump right up to above 500, and itll be fine? .....well thats what happend to me

 

it just jumps around i was doing 80mph and i looked at my rpms and it was at 8,000rpm but it was really around 4,000 and it just bounces 0-8,000 rpms???!!!!!

 

Seems like your guage cluster is messed up if your car drives normally. A few have reported this recently and say that swapping out the guage cluster for a used one from a salvage yard cured their tack yips.

 

How does one clean the IACV?

 

I have the same question, its talked about often, as if its pretty easy, but I've never seen a how to.

 

it's in the FAQ
