I found out today that I have 4 bad injectors, the entire drivers side. I have already replaced two on the passenger side. Instead of buying four to replace I would like to buy a set. I was wondering what kind wil fit my 91 Trans Am 305 TPI. Injectors from what years?? what engines?? and also what is the stock lb/hr rate for injectors?? and how big can I go with a stock computer?? 22 or 24??

 

Aren't the stock ones 19?.
To change to larger ones properly is going to mean doing a chip.
Some guys have used 19 on a 350 by twisting the FP up. Trying to drop though means less atomization, which isn't a good thing.
6 bad injectors?. I'd sure be looking for a cause. ie bad fuel?. somthing.
Have you tried runing some slick 50 fuel system conditioner?.
After trying all the avialbe off the self ones it was the only one that really worked for me

 

Your stock fuel injectors are rated at 19 lb/hr at 43.5psi.

I suggest that you call Rich at cruizenperformance.com and purchase a set of balanced 19 lb/hr injectors and also a Crane or other AFPR.
