High/Hanging Idle - ZR-1 Net Registry Forums

Smoke test was revealing. The MAP line had a tiny leak around the nipple on the plenum, smaller line fixed that. I also can see smoke coming from two locations deep under the plenum. One coming from possibly around the actuator between cylinder 6/8 and the other deep below the injectors on cylinder 2.

Anyone thoughts on what could be leaking in those areas?

Looking at some diagrams, looks like the bearings for the secondary throttle shafts are roughly in these locations.
