Hey all, just recently started to have a lot of idling issues with my ls-t. She idles real bad. I've cleaned IACV, check all vacuum for any leaks, made sure timing is correct, etc etc. I'm at a stand still now and STUCK. I'm guessing it may be Crome and time for a new ems, but I'd rather be safe than sorry. Any help is appreciated. Click on pic below for video

 

have you confirmed the IACV is good ? have you set the idle screw with the IACV disconnected ? When was the last time you check cam timing and also valve lash adjustment ?

I wasnt able to see the video but those are some suggestions

 

Injector battery offset correct? Wideband?

Alot of things here. I found it easy to start with a basemap from Xenocrons BIN dump on their site and go from there when using Crome

 

Started having the problem after what? How is your tune/wideband readings? Have you taken a look at your spark plugs at all? The wires? It's not Crome, haha... even though its not great.

 

Ive had idle issues with crome..

switched to neptune and did nothing to the engine, idle was fixed

 

currently don't have wideband so will purchase one and get car retuned. Will check cam timing. Valve adjustment already done. will update later. Thanks for the recommendations all. Hopefully I can get this thing fixed.
