Idle Fluctuation FIX

Anyone experiencing this issue I encourage you to try this.

I had this issue very early in my FR-S. About 250 miles in and I noticed it the first time. The idle was not steady and it would also drop and just jump up past 1k to compensate.

I took a swing in the dark after someone reported the Perrin crank pulley fixing this issue for them.

I ordered a Perrin crank pulley and installed it. The problem appeared to immediately disappear. 2500 miles later I am still issue free. I would consider it solved.

Interesting! Can you post a link the report? I'd like to read their story too.
