Ford Thunderbird Fuel Injector

Can I Change The Stock Injectors To Larger Injectors. If So What Else Should I Be Aware Of Cam - Timing Or What

I Was Charged 402 Dollars At A Local Repair Shop To Diagnose And Replace One Fuel Injector And Nothin Else. That Seems A Little High,what Is...

Where Are The Fuel Injectors? I Have An Ohm Meter But Can't See Where The Injectors Are Located...

I Put Gas In My 93 Ford Thunderbird And Now It Won't Run. I Replaced The Fuel Filter And Added Heat And Injector Cleaner. What Else Can I Do...
