93 2.5 v6
New cat and still failed. Passed high speed test though. I know my vris #1 is not working, it stays closed on idle, could that be a reason for low speed failure?

I dont think a bad vris could cause u to fail, i could be wrong though. Do u have the PPMs on ur emissions ? That could be a good place to start figuring out what's wrong.

x2 VRIS doesn't even operate until 4k surely? Really it doesn't do a lot. A vacuum leak would cause more bother. Are all the vac lines ok? Intake hose? Got good spark?
