I will give the run down. I have an 87 crx si (first gen) with a second gen B16 in it. I am running the engine with a PR3 ecu and first gen B16 dizzy. I have the high impedence injectors and so have removed the resistor box. My problem is that I am running extremely rich. I have two new O2 sensors and I am not getting any error codes. At idle my air/fuel is right in the middle and as soon as I hit the gas pedal, it goes full rich. Can anybody help me?

 

u could get a fpr and turn down the fuel pressure a bit.

 

See that's the thing. I am running only 31 psi when the engine is running. I forgot to mention that in the first post.
I am going to pull the fuel rail and injectors this weekend and make sure the spray patterns are good and also double check all the ecu connections just to make sure I haven't missed anything.

 

Is anyone there? I could really use some input. Thanks.

I think that is why you should run the resistor box to tune down the injectors.

 

They are high impedence injectors and they wont fire with the resistor box.
Since my last post I have pulled the fuel rail and injectors to check for leakage and the spray pattern. Everything is very clean and working flawlessly.
The second gen B16 came with injectors that do not require the resistor box. They have the proper impedence without it.
I have checked their impedence also, just to be sure that they are within spec.
Do you think that the MAP sensor could cause anything like this?
Running out of ideas here. I may just buy a VAFC and tune it down.
I would rather not put a bandaid on the problem without first exhausting all alternatives.

 

Can't help you, sorry..... This is the reason I went to aftermarket EFI. Got sick of trying to please the f#$%ing factory computer

 

No kidding!
