But did not notice performance increase, still stock idles. Sluggish could be spark, coils, clear adaptations, maybe a tune up with AA. Try inserting your key, turn on the start/stop button (DO NOT press the brake to turn on the engine) instead press the gas all the way down for 30 seconds, you may or may not hear sounds from the radio head unit area to reset throttle setting. Turn off car, wait a minute or 2 I think, then drive around, warm up, red line it safely for a few miles. See if that works.
almost forgot u can try reset throttle without tools
