Ok so as a few people on here know I sucked water thru my intake twice and thought I had screwed the motor up. Well I cleaned my throttle body and holly **** she runs better then ever no more backfires no more bogging down no shutting down when stopping quickly no more engine troubles. Never knew a dirty throttle body could cause all these issues. I have a high idle but I need to adjust the butterfly stop screw but thats will be on a later date.

I removed it and cleaned it with valvaline heavy duty carb and throttle body cleaner. I used the entire can lol. Reinstalled using black RTV.

You can chase butterflys all you want but that won't fix the vacuum leak.

Ever think of bending the tang it rests on to get your adjustment?
