JDM st185 tends to cut out around 6k rpms. Runs strong up until then but once you approach around 6k it acts like it’s hitting fuel cut or a rev limiter or something. I’m running a MBC at around 14psi which has ran fine since I installed it. I don’t think it can be fuel cut anyways as I plugged the map sensor vac line and that had no effect. The exhaust will also sometimes crackle and pop when it does this, but it’s always done that since installing a dp and 3 inch exhaust. The only thing I can think of that I’ve done recently is plug some vac lines for the ac idle valve, Since the valve was broken and I needed to bypass it to idle correctly. It’s not a huge pain as I don’t often go to 6k rpm but seems like a sign of something bigger so I’d like to address it if I can.
Any ideas?
