Idle help

[woody69]

it will start for a second and die and if you rev it up slowly then let off it will idle fine but as soon as you turn it off and start it again you will have to do the same thing. lq9 4l65 with tr224 cam ls6 intake and short headers. I just put a 01 ls6 program in it and still the same thing. although it seems to have more power with this program rather than the truck program.


thanks Woody

Hello Woody and welcome to the forum. I take it you are working with a 6.0 liter truck with a 4l65 and 224 cam. Could you elaborate on your setup further, mods, year/make, etc... Which OS / calibration did you start with and which one did you recently upload? Do you have a wideband O2? If so which one? I am sure we can help you out. We just need more info. In the meantime do a search on Running Airflow In Park \ In Gear (RAFIPN \ RAFIG). I also assume that you have an electronic throttlebody, correct me if I am wrong.

04 6.0 lq9 4l65e from a silverado ss, 224tr cam, ls6 intake, street and performance headers for 1st gen camaro ( I have a 68 Impala that this is in ) 3000 stall 3.73 gears. The os is 12208322 and I am still running the same all I did was to copy with lables and paste the 01 ls6 engine calibrations that I got from the efi live files. I have a cable TB. I do have a lc-1 wb but haven't even had a chance to install it yet. Thanks Woody

My car does the same thing.. I bumped up the desired airflow by 20% it cured the problem for like 2 days but now it is back.. Cold starts are fine.. I only exp this on warm starts.

any other help would be appreciated. After you drive for a while and then start it again it does the same thing.
