On the drive home yesterday about an hour or so just after my second post on this issue.........the speedo needle jumped around a little bit again.
When I got home I pulled the air cleaner, and each coil pack off, and blew each spark plug chamber out to see if there was any water left.
Number 5 cylinder spark plug chamber had a tiny amount of water that blew out, but all the others were bone dry.
The air cleaner was completely black & completely clogged with leaves & road debris so I put a new one in and cleaned out the MAF with MAF cleaner.
I also pulled all the fuse covers off, and all the fusses & fuse trays were bone dry.
I put everything back together, and she idles much better & doesn't sputter below 2000 RPM on acceleration like she was doing after I washed the engine -but she still doesn't idle as smoothly as she did before I washed the engine.
The lesson I learned is that the VSS is definitely not connected to the washing incident because the needle jumped once or twice again coming into work this morning.
I still have no idea what happened to my "Rolls Royce" idle and it's aggravating as hell to not have it but I have no idea what affected it or how to make her silky smooth again.
There is no water........ANYWHERE!!!!!
Right after this post I'll be ordering the VSS repair kit..........
Hope all of this helps future sufferers from this issue, looks like the VSS malfunctioning is independent of other things going on with your engine.
wash your engine no matter how grimy it is, or clean it by hand the old fashioned way with kerosene and scrub brushes like we did back in the 70's...
