Idles so low that it looks like the car died. Only have it gets to running temp though.
Gets worse when i drive longer. It hasnt died yet but its got low enough once that the battery light flashed but i saved it just in time.

No CEL
Clean IACV & Throttle body
Batterys at around 12V when cars off and around 14V when running
Ground from bat. , VC , tranny all tightend and clean looking.

I recently put kill switchs in for my main relay ground and my fuel pump power wire comeing from ecu .. tock them off to see if that was it, butput them back on cause nothing changed.

Adjust the idle speed.

 

With car at normal operating temp:
Unplug IACV
Adjust Idle screw until your rpm's are a bit under 1000
Plug in IACV
Turn off car, unplug NEG battery cable, and pull Back up fuse for ecu (7.5) in under hood fuse box. I waited a few minute and put the fuse back in, hooked up the battery and before you start the car, make sure ALL accessories are off... then start the car making sure to NOT touch the accelerator, this is the idle relearn... I let it idle for about 10 minutes.
Good to go.

Since I have an aftermarket TB, I have no idle adjustment screw. We're supposed to use the throttle stop adjustment. I fought this issue for a while and fixed it today in about 10 minutes. It got to the point where the car shook, and felt like it was going to die but never did.
Hope this helps.

 

When doing the idle relearn, isn't there something in the manual about starting the car with the accel slightly depressed and leveling off the RPMs to ~1000, then slowly letting off the pedal? Or is that only on EGs?

 

 

do i do this with the car on or off
that pic doesnt say anything about unplugging the iacv
