Throttle Body Cleaning

Hello. I've been trying to figure out why my truck has been idling low and constantly dying. After a lot of "research" I decided to clean my throttle body. I opted to completely remove the throttle body. The procedure in the Haynes manual is better than in the factory manual and was actually quite simple. I was blown away how dirty this thing was! I spent at least 2 hours cleaning the throttle body and I only used throttle body cleaner. I only used a clean shop towel and an occasional Q-Tip. I hope this fixes my problem.

My TB was very dirty. The pictures don't show it well. Plus, the gasket was brittle. I gander that this was the first time it had been removed and/or cleaned. And, the two nuts and two bolts were definitely overtorqued! All in all the cleaning was easy except for the cold weather.

It solved my low idle and stalling problem! Next, I had to diagnose and fix my MAF.
