Subsandwich Posted June 1, 2019 Share Posted June 1, 2019 For anyone with higher mileage, having issues with rough idle, a good throttle body clean may be for you. The throttle body hides underneath the intake manifold, but it's a 1-hour job (at least with my FMIC, I would assume somewhat the same with the TMIC though, cleaning the throttle body takes maybe 5 minutes, the rest is removing/re-installing the IC). Engine bay: The yellow circle (where the charge pipe and BPV lead) is where the throttle body is located. Angle from driver side. Charge Pipe/hose removed: With the charge pipe and silicon hose removed, you can see the Throttle Body. And a close-up of the throttle body. Doesn't look like much, but that gunk indeed caused a (barely) rough idle. Took some carb/throttle body cleaner ($4 bucks at Advanced Auto), a rag, and a toothbrush. A quick spray, wipe-down, another quick spray, brush, and wipe-down, and done-zo (forgot to take a pic). $4 bucks and less than an hour of my life and idle is back to nice and smooth.
