Hi guys, I have been searching everywhere on how to adjust the idling on the 3rd gen 3sgte.
I just finish my 3rd gen swap, I change the spark plugs and clean the throlle body already. My car idles at 500 on start up and normal temp and it should be at 800 @ start up and 700 at normal temp. any ideas on how to adjust the idling to 700. Please help... |

Idle is controlled by the iac valve under the throttlebody, and ecu.
You shouldn't have to adjust it manually. I would clean and lube the iac, and check timing. Both can affect idle. -------------------- Former Team 5SFTE pro member ;)

you can adjust the idle by changing the rotation of the throttle position sensor. (TPS)
the mechanics plugged into the diagnostic and checked the throttle and adjusted the TPS. Not sure about the exact details but at least it's doesn't stall like it used to. Probably reset the ECU too. |

I advance my timing by a hair and now my car now idles at 500 at cold start and idles at 5-600 @ normal temp.
it runs good now but there is something weird going on right now. my car runs with no check engine to start and after a few minutes of driving, the check engine light comes on. what do you guys think? |
