  1. Im replacing a manifold system and would like to know how do you know when it is time to replace the Injectors...are there visible sign's or what please respond... :flag:
     
  2. Well
     
  3. Up to 300HP the stock 19# injectors are good - a simple intake swap won't get you there on an otherwise stock engine.
     
  4. I think he means... do they go bad or need cleaned? How do you know?
     
  5. get a long screwdriver or metal stick and while the engine is running put one end on an injector and the other end to your ear,(make a fist around the end and then fist to ear, dont put the stick in your ear :p ) and if its ticking nice dont worry about it... and clean them anyway... injector cleaner
     
  6. Whats the best way to clean an injector while they are out of the intake? I'm doing an intake swap so they'll be out anyway. I'm injectorilliterate
