Weird car problem

[jbach36]

The other day, my car began to shake a bit when idling down to a stop, just a little bit like it's going to stall out. I thought it might be the fuel filters, so I changed both of those, still same problem.

I guess next up, is to clean the injectors, is that correct? Is there any way to "clean" them by dumping something into the tank, or must I do that lubro Molly thing?

Thanks,

Jeff
