Exposing my throttle body, I found it to be a greasy mess...
-Does anyone know what this substance is??? (oil, carbon residue, fuel)
-Is it something I should be concerned about???
-If it is a normal occurrence, does anyone have tips on how to prevent this mess followed with cleaning methods???
For my 1994 Jeep YJ Wrangler Sahara Edition 4.0L (Only the best for my Jeep)
Thank you in advance!!!!!
