Default Throttle Body Cleaning

This is for an '08 Impreza 2.5i.

Few weeks ago my car didn't wouldn't crank. After disconnecting the battery and reconnected started up fine. Took it to the shop just as a precaution and they didn't find anything but replaced battery terminal.

Happened again the other day. Got it to start by disconnecting and reconnecting battery (separate issue but seems odd...).

Anyway, after it started up I'm getting a really low idle (~400-500 RPM). From what I've read on here cleaning the throttle body helps issues with low idle.

Are there any guides on doing that?



I thought this hose running from air filter was it but apparently not.....

Need some newbie help.

Your throttle body is attached directly to the intake manifold. See where the tube comes from the box to the manifold? Your throttle body is at the end of it.

To clean it remove all the connections and hardware, take it off, spray it with throttle body cleaner.

Where are you located, OP? That is one dirty ass engine bay. Check your air filter. Check the MAF sensor. Check the TB. clean all of them.
