whats up yall. alright, i have an lsvtec turbo setup. my problem is that when my car reaches regular temperature, especially when coming to stops, my car will idle real low and kind of struggle to get back up. once it recovers, it idles fine. well, just recently i put on a breather tank that runs from the back of the block and from the hose on top of the pcv black box. now i dont think this is causing a problem but i have no clue. also, i ran the bov vacuum line to the vacuum port on the intake manifold where the pcv hose used to be. does anyone have any ideas what could cause this idling problem?

 

any ideas?

 

bump

 

Has it been tuned? Many times I see people turn their IACV duty down and have the same problem.

Otherwise look for the obvious- vac leaks

 

yeah its tuned. got it tuned during the winter. yeah ive checked for vac leaks but everything seems good. ill look into the IACV but the car doesnt idle irratically.

 

Do you have a wideband on the car?
If not, get one & let us know what the air fuel ratios are at an idle.
