98 Legacy GT, with a 95 EJ22 swapped in.
Every so often, the engine will just start to misfire and run very rough with no power. If I shut the engine off, then turn it back on, everything is fine again. It started over a year ago, but almost never did it. In the past 2 months, it's done it more often. It does not flash the CEL when this is happening.
And since I can't figure the source of this misfire, here 2 other things the engine is doing:
When going down a hill, and engine braking, then getting on the throttle, it smokes for a bit burning off some oil. I suspect valve stem seals for this.
It is also using a bit of oil, which could be tied to the valve stem seals.
