So my idol is so bad that any time I stop the idol bounces terribly, and stalls.. Now I have loud knocking in the head (Maybe loose lifter?) also when cruising or taking off the sound of my car is a purring sound not a normal "humm", or "rumble" (fowled plugs maybe?) I did pull em and they do look bad but think they have around 40kish miles on them which isnt much.. but I got some Ngk 2 Step Colders coming in the am. Lol might be easy fixes but very overwhelming and frustrating to say the least... Anyone else having similar problems? and maybe fixed the issues? or any thoughts? please, and thank you.

 

Me. When i stop and hit the clutch oftentimes it stalls or atleast does a lot of idle bounce. The knock may be engine knock because in starting tot hink the engine gets leaned out when this happens. No i dont have much advice yet. Is your car stock?

 

replace your timing chain tensioner. that would do it. it could be loose which could cause the knocking and rough idle

 

also, if you're still on 42's with a 2.8, i HIGHLY recommend getting 60's or higher

 

Check for a vac leak, i had a hose come loose and had a nasty leak, i had misfire on cylinder 1 and my exhaust had a pop noise to it, my idle would bounce every now and then and james help me figure out the problem and all my **** was cured

 

lol not it will make noise but dosent affect idle

op you dont need 2 step colder plugs get your tune looked over and look for a vac leak
