at 27 seconds you can clearly see what im trying to say!

 

what kind of bov do you have?

 

i have a tial bov

1250cc injectors
MAF with 3" piping from maf to turbo inlet..

 

check all the vacuum lines, Whens the last time you had a retune. My car use to do the same exact thing. Never fixed it though.

 

i checked the vaccum lines and they seem fine,and i tune my self, i think my problem is related to IAC valve maybe it needs replacement but before i do that i want tknow other possiblities,,,anyone here facing same problem and over came it?

 

my car is doing this for awile now but recently it got to my nerves as it kept stalling on low rpms while driving...

 

My car does the same. Volt test your IAC and see if it's bad. Also your afr at idles was around 10-11 is that normal for you?

Also could be your throttle body seals

 

no no my afr's are at 14.7 to 15.0,its just that when i rev they go to 10 and stay there for a few seconds and become normal again...

how do i volt test it? can you plz explain it to me?

 

if i clean my throttle body will it help with the issue or is it a waste of time?

 

I am on my phone so a pita. Search for threads under my name. You will see and idle thread there is a link on how to test the IAC valve. Can't hurt to clean te TB I also cleaned my MAF sensor

 

thanks alot dude, just one thing...can i use wd-40 to clean the throttle body or a lil bit of gasoline cause over here we dont have throttle body cleaner? although we do have carbruretor cleaner if that works?

 

bump!

ok can i use carbuerator cleaner to clean my throttle body?
