i cant figure out why its not doing it anymore. A couple of days ago i cleaned the throttle body and MAF sensor with STP throttle body cleaner and CRC mass air flow cleaner. I disconected a few sensors to do the job and removed the MAF sensor to clean that but left the throttle body connected. I put everything back together and started the car, it ran rough at first and stalled (i think it sucked in a little throttle body cleaner) but after a few revs it was fine, i made sure i blew it all out on a open road. Then up until today i noticed it wasnt making a WOSH! sound anymore when i shut the car off. No SES light or anything and the car seems to run alot better, this worries me a little because its a sound that i am used to. Any thoughts?

That "whoosh" is the sign of a dirty throttle body.

haha! wow i feel stupid lol. u learn somthing new everyday i guess. thanks sabrewings

Well my car defiantly makes that sound when i turn it off. If by the "WOOSH" sound, you mean what it would sound like if the car took a deep exhale?

Then, how might i go about cleaning my throttle body, just pull off the screen , or are there things that might mess it op?

You can try just taking off the screen, but most of the crud is on the back side...

Here's mine at 68k miles (back side):

Is it worth cleaning, should i take the thing completely off and clean it up?

I'd say it's worth it. It made a lot of difference on my truck when I did it. I would've done my TB when I had it off, but I didn't have TB cleaner and I was currently waist deep in another project.

I'm going back in tomorrow to clean the TB and EGR.

screen?!?! lulz are you f'n serious thats like the first thing I rip off, cuz it blocks half the air going in the engine, 110% better throttle response.

Yeah, it's there for a reason. Smooths out airflow across the MAF. There is practically no loss of flow with it in there (been checked on a flow bench) and the potential downsides are serious.

Chipped piston with .00021% greater airflow... or safe pistons.... decisions.

Use SEAFOAM



It cleans alot better, has multiple engine uses, sure the car smokes alot when its done however if there is no smoke it aint clean.

very very similar to the pro injection/upper intake cleaners.
