Can idle be set too high and cause a racing sound in the engine?

Wow...Wheel bearings CAN make the engines RPMs race? Who will win? And he needs to do a "test-drive" for an IDLE issue? WOW...Teach us some more of your funky tech stuff! . . . I find it credible that a clown like witfry12 would come up with WHEEL BEARINGS affecting the idle...maybe smaller bearings would lower the RPMs?

HEY , you must've been working on cars for at least a week now! Sorry to disappoint a genious , but the description given is one of the most common we hear , from people who don't understand WHAT they are hearing. Let's wait to hear back from BobbyKayL......I find it amusing , that someone that posts a 'profile' like yours , would be so insecure as to feel necessary to belittle so many different people whom he's never met , and so inexperienced to believe that an IDLE air control valve is affecting the engine speed WHILE DRIVING , as the post states. your.mechanic.........won't you be my repairpal??????????.......Grow up......your getting boring....still entertaining , but boring.........never mind.......
