i have recently purchased a 1996 blazer LT, now i only spent $850.00 on it but its missing on cylinders 2&4 now my mechanic said it the injectors. but i was talking to one of my friends that also own one and he said that he had the same problem and all he did was replace the pressure mod and plugs wires cap and rotor so im not quite sure what to do can somebody please help me if you've ever had this problem or know a solution, i realy dont wanna be playin the "lets see if this works" game i just want to get it right with out spend a tremendous amount of money

 

go on amazon spend 180 for a new delphi or delco spider unit and be done with it,comes with new regulator. that age and amount of work just do it u cant go wrong, reg alone is 70 bucks easy choice imo
