hey I cant find any vaccum leaks and car just constantly goes from 700 to 1300 every time its at idle or if i have clutch in...any ideas what it could be?

 

it also doesnt throw no codes either

 

Anything you've done leading up to this issue?

Why dont you try unplugging your IACV and see if that fixes it. Doing that is like you're going to time the car and if it idles ok like that I would clean out the IACV and then try again. That's a common problem w/ an easy fix.

If its not that I would pull the carpet back and double check to make sure you don't have a code. You may have one without a check engine light.

 

carpet been pulled back car is kinda ghetto right now lol in process of restoring it but i unplug that in the morning and go from there i guess

Check it for flashing. Also try resetting your ECU that may help. Pull the hazard fuse for 15 seconds or discconect your battery for a bit (if you dont mind loosing your radio presets). Disconnecting your battery will destory your long term map which may lead to a little performance difficulty though.

 

cleaned out my iacv and still idles up and down...i just want to blow my car up sometimes

 

CHECK VOLTAGE ON YOUR THROTTLE POSITIONER. I HAD THE SAME PROBLEM , MY VOLTAGE WAS AT 1.3 VOLTS WHEN IT SHOULD BE BETWEEN 5-7 VOLTS. THIS SHOULD FIX IT RIGHT ON UP.

 

check if your IACV is actually getting HOT water to it.
Sometimes old pipes block up, there is a bend and the water doesn't flow through.
