exhaust? I thought before i took on the task of replacing the fuel pressure regulator i should take it to somebody that know about injectors and that could check them. They said the regulator was fine and the injectors failed the test. cylinders 2,6,8 were all 3 pounds under they said. they said the injectors were causing the backfiring, rough idle, strong fuel smell and poor gas mileage. I wanted to run this buy you all that gave me the good advise before. Hopefully you read this GSD PAL, GREASRA.... and CHEVYRACER. Thank you all. ~ Kurt
P.S Those injectors are SOOO... expesive. You all recommend a certain injector? Cheap that will work??
 
i would check your plug wires and plugs before you do any thing major could just be your carb.
