I don't know what size injectors are on my car, the number is
9199 17086542. they are blueish and are on a 1990 camaro 350 tpi and should be stock, but i know the 350 has 22lb injectors stock, but my car was originally a 305, so I'm not sure.
thanks!!

 

try gmparts direct or call a local gm dealer in the morning either on should work.
