Ok hears the problem over the past 6 months the car has had low power it starts to give up a 3500 and sputters at 4300. I have a new coil, cap, plugs, o2 sensor the injectors spray good and I notices a taping coming from the right side of the motor so i readjuster the rockers but it is still there. could it be the holley intake i put on after that the power was gone? Its the 89 if you look at the sig

 

is the egr the source of the tapping?

 

Shouldn't be. Check the fuel pressure at the feed line. Even when my fuel pump went out my injectors could still spray the dying 6psi evenly.

 

Check your timing.

 

I have no egr, I will check the fuel pressure and the timing is at 3*. I put wires on it and it runs good but still not happy, it's ben dieing on me allot and I don't know why?
