There is some excellent info in this thread. Thanks guys
I think this will be my next maintenance project. It will give also me a chance to deep clean my intake filters with some Simple Green solution
I'll be sure to post my experience as soon as its done. I am hoping it helps my idle, which seems a bit "off" lately.
btw, KeVoH, it is unlikely that cleaning the TBs will make your car more responsive. The intake manifold you installed is the reason it feels that way. You should feel it pretty good in the mid range and with a tune it should improve across the board.
