at normal running temp the car is idling between 1200-1500 up and down
i have adjusted timming its at 16 degrees an i have adjusted tb and its turned all the way down thats bout the lowest and best idle i could get

it does not have bad idle when the timing was way off set for top end
that was not my doing some fake *** machanic did that when the motor was in my teg(R.I.P)

i notice alot more power when i corrected it but then the bad idle was back

please help me out im tryin to sell the car an nobodies gonna buy it idling like that

i had the same prob. it was driving me cazy.
I found a loose vacum line on the intake manifold.
The one that connects to the charcol canister.

just curious.
Do you have the stock ls manifold?
Have you bypassed the coolant lines at the tb and iac?

1 more thing did you reset the ecu.

STPREZ

i will check that hose

yes i have stock itk manifold

i used to have those coolent lines blocked when i was using sohc throttle body with external map but after a while i started getting check engine light so i put ls tb back on

you think i should block those hoses
should i just take them of tb an block them off
or block the holes in the tb(thats how i had it in the dx tb)

b20z2

no don't block them.
I was just curious.
Hope you find that leak.

(when i was using sohc throttle body)

if you were running with that tb and changed it, did you replace the tb gasket?

STPREZ

ya gasket an all was changed

i checked the charcol canister it looks good

all vac lines i see look good
could it be the iacv
i really dunno how to check that (the haynes manual sucks on info theses days)
