Any long term damage to be done? I've had a high idle problem with my car since I bought it. I swapped in a used part over the weekend with no change. It would idle close to 2K in park, and drop a little when in drive. Once I ran the car with the partdisconected, the idle seems to be around 800. Do you guys think there would be any harm in leaving it disconnected? Thanks.
