Ok, so i bought my bronco and have been driving it for a little bit now. I like the way it drives, but i think there's something wrong with the motor. It seems to me that it is idling a little bit too high, and when i put it in gear the rpm's will drop down really low, and sometimes shut off. I took it to my local auto parts store. I told him about what was going on, and he told me to take the upper and lower intake's off and clean them up with a can of brake cleaner and a wire brush, like what you clean out a shotgun with. I've never heard of this being done, and i don't know if it would help or not. What do you guys think?
