The Silverado's idle has had the funk for the past week or so. Dropped down after starting and then engine stall.
This morning I cleaned both the MAFS and the TB with this cleaner kit from CRC.
Neither one was super dirty but did have a light layer of soot.
So far so good. Engine idles as it should.
I also dumped some fuel additive in the tank while I was at it.
I just set an insect fogger off inside because I was starting to get a few roaches.
