What's up people,

Ok so I am going to get a tune in the next week or so, and I need to know what injectors are in my car. I know the stock ones have green tops. Mine are black. Do injectors have serial numbers on them? Or part numbers? I know the car at one point had a gm stage 2 ..and the engine blew up with that on it. So I wonder did they put the injectors from the original stage kit in the new engine or dose it have stock cobalt injectors not lsj injectors. Any input would help before I haul the fuel rail off and take out the injectors. Thanks.

You think? Would gm use them? There isn't any markings or numbers on injectors? I'll have to take them out and take a picture ...fml.

green injectors are stock gm 33lb, black tops are stage 1 or 2 42lb. if the car is running ok and it had the gm stage kit on it, they likely swapped the injectors to the new engine. running smaller injectors that what the ecm is tuned for will cause an extreme lean condition and would likely have fuel trims maxed at 18% and code p0171

Superbolt

Not the best of photos, but since the stock injector harness is still in use, and I can see a portion of the injector, I can verify they are GM Stage Kit 42 lb/hr injectors.
