2004 1150 twin spark. Every time I tuned my throttle bodies previously, the BBS were about 3/4 of a turn out from bottom and fairly close to each other. The last time I went for a ride, the idle was at 1400 when I was done. It's done this before, but only up to about 1250 after a good hard highway run and always came back to normal afterward. Now it's hanging around that 1400 mark and i can't get it down. I turn the BBS almost closed to get it down a bit and now they are a full turn plus apart from each other when balanced. I pulled them right out and they were fairly black, cleaned them and sprayed throttle body cleaner in the hole and no change. I thought maybe a stick coil was goofing off, so I uncapped my secondary plugs and it made no difference at idle. What next? Any suggestions are appreciated.
