    Hi Guys,
    I just finish installing 2007 TB Tundra on 2nd gen with URD adapter TB plus with K&N 63-9037, the idle between 800 to 1k on warm engine but once I turn AC on the idle back to 600 to 800 sounds normal to me only when I drove it and stop at traffic light the idle take longer to normal state. Another problem comes out with the code, P0505,P0102,P0113,P2433 and P2438 all connected with I just install I clean the code but they coming back, so I don't know where to start fix it or change it. Do I have bad TB Tundra maybe?
    Any input will be appreciate it. Thank you Guys

    There's a set screw covered under a blob of epoxy. If you back it off about a full turn it improves the idle.

    The ecu takes a while to learn and smooth it out somewhat.

    Yeah running same on my SC'd truck. I believe manual trans trucks have more trouble with the idle with those throttle bodies. Also, I'm tuned with Hptuners and JustDSM made some adjustments to the ecu to for the throttle body.

    I did have some weird issues and codes at one point that a battery disconnect ended up solving as well

    I try the screw under expo back full turn not much different even all the way until I take it off the idle still high, only when first start is work but after drive little bit back to high. The code coming back but I take negative cable from battery and wait 20 minutes see what happen.

    I did many times not success but the last one is work, right now around 600 to 800 but I turn the AC on the idle jump into 1K , still not consistent idle .. need figure out to lower when the AC is on.
