How To Clean The Throttle Body On Subaru Baja

My 2003 cold started swell,idled fine too.

Later on it would reach to operating temp information technology would driblet RPM and stall out when I lifted off the gas between gears.

I have a 5 speed and it'due south a very common cold spell in Jan. I alive in MI.

Turns out the Idle Air Control Valve was my problem. The plunger had carbon on the tip and the Throttle Torso had some within also.

This would not allow information technology to shut all the manner creating an "Internal vacuum leak", Leaning out the Fuel Air mixture that the computer could not compensate for.

Hither is a dirty plunger.

Here is the muddied T/B intake port. Note all the grey textile,looks like moon dust LOL. Also notice the ii screw holes...

SO let'due south clean yours.

First disconnect the electrical connector at the base of operations of the IACV. And then spray a penetrant where the blue arrows indicate, This is the open end of the two screw holes you lot've seen above.

At present aluminum and steel like to bond together over time.

Use a apartment blade screwdriver and a hammer.

Put the screwdriver at the cherry-red arrows, Hold it firmly and then utilize twisting force while you hit the handle with the hammer. This will send a shock downward the screwdriver and so the screws and aid pause the bail.

Remove both screws and get the IACV off. Proceed an eye on the small orange O-band that you meet in the dirty plunger photo.

Seafoam,WD-forty,Lead Blaster...almost anything volition piece of work for this. Spray a rag down and rub off the tip of the plunger and the base stem too.

So spray the TB port and stick your finger in the rag and rub effectually the port. If you accept a pocket-sized plastic bristle brush you lot tin use that too.

Next apply a very slight amount of anti-seize to the screws at their finish. This will elevate it over all the threads when you reinstall it.

Assemble is the opposite of removal. Tighten it snug,reattach the electrical connector. And you're good to go.
