I have a 91 camaro with a 305 tbi, I've been having tons of problems recently with the car running rough and dying on me at low rpms. Here are the parts I changed with no improvement on the car.

EGR Valve
IAC
MAP Sensor
Coolant Temperature sensor
Sparks/Wires
Pickup coil/module
Rotor/Distributor cap.
Injectors
ECM - Probably going to return cause it made no difference.

Tested the fuel pressure and got the recommend 9-13 psi, getting spark and fuel. I'm out of ideas, what do you guys recommend?

 

Check for vacuum leaks!
Check your TPS also.

 

Ohm your injectors, should run about 1.3. Check the injector spray pattern, should conical and even. Rebuild your throttle body, FPR may be ruptured. Check your timing. Good luck.

 

I checked for vacuum leaks, I may replace the hoses just to be sure.

I replaced the TPS as well. As for the the ohms on the injectors, I checked those and they were fine. I rebuilt the throttle body and put new gaskets and a new FPR. Timing was just recently done as well.

Any other ideas? Hahah

 

Check for vacuum leaks again. While the engine is running, spray a small amount of starter fluid around all the hoses and intake gaskets and see if your rpms rise. Just don't spray any on your exhaust.

 

Did you disconnect the EST wire to set your initial timing? Also might want to consider having your ICM checked, didn't see it as one on the items replaced.
