Just like the title says, my idle shackes the hole car bad. and then when i step on the gas my flowmasters making a bubbly kinda sound. like not smooth, like when you push the flows really high and you hear a crackling when they are coming down kinda sound but when you step on the gas. This started after i drove through some water. My flowmasters have turndowns so i was thinking maybe some water got in them, but when i went to take em off to tip em over to see if anything comes out. the ppl who out my turndowns on put a small spot weld on the bolt holding the bracket of soo i can't get my flows off the see if their is water in them. WHat should i do??
