[QUOTE="RaYzerman19, post: 1340127, member: 18388"] The codes 11 & 12 could have appeared if the ECU thought something was wrong but wasn't, I've experienced this before. That's why you clear them and see if they come back. To erase, while in dIAG, scroll to 62 and switch the stop switch and they will clear. To remove the spark plug boots, unscrew counterclockwise while pulling/working the wire out of the boot. Once apart, you will see the screw, trim, spread the wires and reinstall. Perhaps redo the TBS, suggest verifying that #3 screw is 3/4 to 1 turn out so you can better balance the others (sometimes Yama had #3 less than 3/4 turn out). May help, may not. Turn the idle adjuster out so the idle drops, then turn back in just enough to get 1100. Another possible issue with idle is that the throttle cable freeplay was adjusted too tight. Adjust the cable so mostly all freeplay is removed but has a smidge of freeplay. Try all these, go for a short ride and see where you're at...... [/QUOTE]
