Throttle Body Cleaning


Recommended Posts

I just followed the great throttle body cleaning guide in the DIY forum. I should have done this a few weeks back, when I replaced the MAF and had the throttle body easily at hand - but I didn't see the DIY for this until yesterday. Went to autozone and bought some carb cleaner, hauled out the MAF again (there's only one bolt, the MAF sensor, a couple of cable holders for the MAF sensor, and the oil filler tube to negotiate - it's 3 mins for a novice going carefully). Got to the throttle body and boy it was dirty once I got a look by opening the butterfly with my fingers. Squirted in a good load of carb cleaner, wiped it out, squirted in some more and gave the inner body and the rim of the butterfly a good cleaning. A ton of dark carbon build up was in there. Went for a trip down the road and VOILA!....a noticeable difference already. You have got to do this!

It certainly doesn't do any harm, which is why I'm gonna do it every 6 months going forward (Spring and Fall (Autumn)) and if you do happen to have some carbon build up in the throttle body you'll definitely notice the difference. Idle's MUCH better, as well as the noticeable difference in pick up.
