IM NEW IN THIS FORUM SO I WAS WONDERING IF ANYBODY KNOWS WHY MY 91 CIVIC WHEN I START IT AFTER SITTING FOR ABOUT A MONTH AT RUNS LIKE IT GOT A MISS FOR ABOUT 20 SEC. THEN IT RUNS FINE?

NEXT QUESTION IS AFTER DRIVING MY FOR ABOUT 5 MIN OR LONGER AFTER I SHUT IT OFF THEN TRY TO RESTART IT IT WILL START THEN DIE. I WOULD HAVE TO KEEP REVING IT THEN IT WILL IDLE. I CLEANED THE ICV. STILL SAME PROBLEM.

1991 CIVIC DX WITH D16Z6 SWAP
THANKS

 

maybe bad gas?

 

First, turn off the caps lock. Did you set your timing? Maybe you have dirty or sticking fuel injectors. I would pull them and get them cleaned and balanced.
