Dirty throttle body?

Hello,

My car has an issue when only on idle, it becomes very hard to turn the steering wheel. Almost like I loose power steering. This is more noticeable when its cold outside. I took it to the mechanic and he said the issue was a dirty throttle body. Cleaning it seems to have made the problem go away for about a year and a half. Now the problem has returned. Does anyone have pics of it's location and how to clean it? Should I replace it instead? Has anyone heard of this before?

It's a possiblity that can happen, and rare that it does. Here are a few things you can do to prevent this from happening again:

- Change air filter regular
- Change the PCV assemble every 40k miles
- Clean the MAF sensor during filter changes

The main throttle body is located after the intercooler, follow the hose from the intercooler to right beneath the intake manifold. There you will find the throttle body housing.

Thank you, I'll try all those things.

It happens more then you think, i work for Subaru and sometimes even cars after a battery replacement with 30k miles run really rough and sometimes die and after a throttle body clean runs like a champ. We usually recommend it every 60k with a fuel system service give or take. And do what f1inspiredlgt said haha

Could be and probably are the OCV's. Need to be replaced.
