RE: Just got my RS4.. need help
I dunno, check your throttle trim and see if it is all the way up. If it is, turn it down some. It should be at the point of revving the engine almost enough to move the car forward. If the car starts to move, turn the trim down a little. Could also be a sticky carb, bad servo, bad transmitter, misaligned throttle linkage, idle screw opened way out. You might have to do some homework, LOL.[&:]
