So I installed my 703 injectors that I got from the junk yard. I installed new rebuild kit in all of them. O-rings and filters. I put them in. I decided not to reset PCM after I was finished.
I started it up and it ran wonderful. I drove down the street and everything was perfect. Could tell the difference instantly.

When I got back. I put it in park and revved it up and then it started missing and rough idle. It was running stupid rich. Smoke and all. So I reset the PMC and its still doing it. weird to me because it was perfect for the first five mins or so and ran wonderful.

What do I need to check?

 

Fixed:

Had a bad injector. One of them was sticking open. Got it running good now. Still running a little rich. Not worried about that as it should get better once the PCM learns after the reset.

I knew I bought 7 injectors from U-pull it for a reason
