hey guys so i recently just finished my sr20 swap into my s13..

when i started it up for the first time surprisingly it cranked over a few times and fired right up! but it idled like shit at over a grand 1100-1600.. sounded like it was missing heavily, and overall not a smooth start or idle at all..

I made sure the timing was correct, the CAS was set to fsm specs, and it was getting gas and running a bit on the rich side. when i gave it gas it continued to miss and chug but when it decelerated after letting off it came down smoothly and didn't really have any miss?

any help or info on this would be appreciated.. thanks !

did u by chance check for vacuum leaks and make sure that all the vacuum hoses are connected right.

Most of the time rough idle means vacuum
Leak.
