Mystery vibration at 25 mph can't be diagnosed. It's not the front end!

Yes, the shop stated the obvious, which everyone here agreed on..............then refused to try a diag. technique, which everyone here agreed it is,........................
for someone unable/barely able to do so themselves,..and you..................View attachment 1715094530about that part.
How long could that've taken them to do for a customer that can't? That was the point. I guess I'll stop using jumper wires in relay sockets to diag. 'cause a jumper wire
ain't a fix.......................or shooting a squirt of brake clean in a non starter to see if its not getting fuel cause I can't keep up with the car can in hand.......................

I think we both agree that we agree, so why the apparent argument? I also agree that the shop was pretty sorry for not trying the washers. 10 minutes at best. Pitiful.
