hey i have a 1994 integra rs wit a grs swap and i just put a cataylic
converter on and i was just wonderin if it will pass my emission and my check
light still comes on

Well if your check engine light is coming on, it means there's (still?)
something wrong, and it will very likely affect the emissions reading.
Perhaps you should get someone to read the codes and find out what the
problem is, rather than just throwing random parts at it?

 

is it likely that it the check light is on becuz of tha engine swap?becuz
tha shell is a 1994 with a 2000 gsr motor

 

/what/ is the freakin' "c0d3"??? "becuz" you're wasting our freakin'
time without it.

 

Werd.

And yes, if you didn't swap in the appropriate ECU for that motor, that
could very well be why there's an error light, AND why you fail the
emissions test.
