I took my truck in to have them check for some slop in the front end. Of course, all was "within spec".
Should have bet on that. Anyway, among a few other things that I know I need to do, they suggested an "injector flush". He told me they disconnect the rail or something in there and run a chemical through the fuel lines so the truck is actually running on the chemical. Has anyone heard of this? I've used PS in the grey bottle and also Seafoam. Is this just another way to separate me from my money?
