I Was Driving Home One Day And The Old 88 Astro 4.3 LTR Started Losing Power And Blowing Black Smoke Out The Back And I Barely Made It Home. A Mechanic Told Me To Put A Fuel Pressure Regulator In And I Did. Still No Good, In Watching The Fuel Injectors Closely While Trying To Start It Lots Of Gas Was Spraying Out Of Them. Do I Need To Buy New Injectors? If Thats Not The Problem Then What Else Could It Be?
Help!
