    Installed a TRD Supercharger on my truck with out any real hitches. The only real problems that I ha e is that it idels high at 1250 at regular engine speeds after its warmed up. Also when I shift it will idel up about 200 rpms then shift. Any idea what the problem could be? Reversed vac lines, messed up maf sensor, throttle body, or just needs seafomed? Any advice or opinions are appreciated.

    Forgot to mention I have a 2003 3.4L. So I don't think it needs flashed or am I wrong?

    if you have a vacuum leak it will idle high and higher when no load is on (between gears while shifting). Are you sure you installed all the vacuum lines? I start the engine and use a propane torch(not lit) pointing at all the points where a vacuum leak could be, waiting to hear the idle jump up. Good luck!

    Could just be the truck getting settled back in after having the battery disconnected and the engine all torn apart. Give it a little bit and see what happens.

    (My 4.0L idled at about 2K for the first three start ups after my headlight retrofit...I had pulled the injector resistor pack and it had to "learn" everything all over.)

    Thanks for all your help fellas. Ended up just being 2 pvc lines unplugged. Not sure how I missed them the first 3 times I looked at it but now she runs like a rape date and sounds real nice too.
