I did a throttle body tear down thread. Not sure if it included removing the throttle body.
@Mufudzi Gambizi (Hope I got ya last name right dude) has a few good VE vids on YouTube that show the same engine. The throttle body removal will be part of one or two.
It’s held on with 4x 10mm bolts.
The wiring needs to be removed first.
There’s a clip that slides out then the plug can be released.
Clean the bit the air goes through with throttle body cleaner. Wear gloves. Don’t open the butterfly with your fingers. Leave it as it is.
Use an old toothbrush to loosen any gunk.
I use Suburu top end cleaner in the intake. I get it from Suburu. It’s a foam. I fill the intake behind the throttle body with it and let it sit. It will clean off some of the varnish and schmutz that forms in there. The car will chug heaps on start up and come good. Might be a heap of smoke and it clears.
New air filter and MAF clean has been mentioned.
