When I chop the throttle, it will either kill or go to a lower idle speed than it would normally idle at. If I close the throttle slower the engine will go back to the normal idle rate. What causes this and how can I tune it out?
Too lean low and your engine is overheating after a full throttle run. that causes it to die on idle. Like others recommended, richen your LS. 1/8 turn out will prob right on the spot. Then let the engine run 10-20 seconds full throttle and if you notice a decline in rpm, open your HS 1/16 of a turn.
