Default Throttle Body Cleaning

I'm attempting to clean my throttle body and I know someone posted a detailed 'how-to'; anyone have a link to that?

I skipped the whole Sea Foam part. Don't really think it's needed and didn't wanna risk the hydrolock. It still made a helluva difference, runs a lot better and got rid of the small vibration I was having.

I also cleaned the MAF sensor with CRC Mass Air Flow Sensor cleaner. And wore some of those yellow rubber kitchen cleaning gloves when I was doing the cleaning.

What other symptoms did you get that may have been linked to the carbon buildup?

rough idle. It acclerates a lot better now also, just runs smoother. The whole process is pretty easy to do. I was actually suprised by what cleaning the TB does, I wasn't really aspecting to notice much. Mine was pretty dirty though, it's an '05 with 34,500 miles on it and that was the first time I've cleaned it.

is it absolutely necessary to disconnect the battery when doing this? i have an interlock on my truck from getting arrested for DUI and im not supposed to unhook the battery because it will screw it up or erase the memory in the interlock im guessing... i mean if i dont have the key in the ignition there shouldn't really be any power going to the sensors anyway.

Just remove the PCMB fuse before you remove your TB and make to re-install it when your finished!

The fuse box is next to your battery. Under the fuse box cover is a map of fuse locations. Find the fuse labeled "PCMB".
