I have just finished installing a new (used) throttle body which I cleaned and followed all the directions this time. I also put back on a mass air sensor which was also cleaned by recommendations from here. So the engine starts great runs good no check engine light on but the idle runs high like at around 2000. If I put the truck in drive and keep the break pressed down the RPM's drop to around 1000. When I put the throttle sensor back on did I do something wrong? can I adjust the throttle from the unit itself? <img src="/forums/images/graemlins/scared.gif" alt="" />
