I have had this 62mm throttle body from LFP for about 6,000 miles now. The car has ran great with it until last week. I started noticing a strand tapping noise when I cycle the key to ignition #2. The cars make a throttle sweep everytime the key is cycled from off to on. This lets the system know the voltage and travel. The tapping noise was the throttle binding. Then today the car when into limp home mode. I tryed reprogramming, but that did not work. I installed the factory throttle body and this fixed both problems. I noticed that the moved on the LFP throttle body it was not smooth like it was the day it was installed. So the guys at LFP are trying to figure out what the problem is, they said that the was the only case of this happening, but I had one of the first ones. It sucks now because that throttle body is good for 12hp and 10 torque. I dynoed it. The throttle response was better, so hopefully I can get a replacement. If they are not going to give me another one then I guess I will go with BBK. I also noticed I good bit of play in the secondary gear inside the assembly, this is the gear that couples with the gear on the electromagnet. The gear is suppose to move up and down but not side to side. That is why it is binding up.
