Am I running on:

I just wired in a set of 88 RX7 injectors (Non plug n' play, accident, but they came with clips and hardware so I don't mind). I wired in the clips and it does start right up... Crappily.

Unfortunately I was looking at TSMS but I forgot to start datalogging.

 

Sounds like all 4 to me. One is def off though.

Also, tell that woman to shut up!

 

What could cause this? It was running fine before the swap. Sticking injector?

Also, that's my sister, lol.

 

This is why we always say to get the injectors cleaned before installing. One could be straight up clogged for all we know.

 

How old is she? And Pics?

How old are your spark plugs? I had one that would repeatedly foul, even though it cleaned up and looked perfect.



Now post pictures of your sister.

 

19, and you don't want pics.

Plugs and wires are ~1,000 miles old.

 

Ok so I'm gonna go test it like this:
Remove spark plug wire 1. Start engine.
If it runs worse, replace and remove wire 2. If it runs the same, it's that cyl that's the problem. Ect ect... Sound good?

 

Yup.

 

Cyl number 1 is not working. I'm guessing a dead injector.

EDIT: Switched out the injector in question to cyl number 2, and suddenly that's the one that's not working. How can I test if it's stuck closed or just dead?

EDIT2: Injector was stuck closed. Carburettor cleaner and a little bit of prodding fixed that.
