Question The problem, help.

Guys help, when you start the engine, the first 5-10 seconds of a stable engine speed, then everything returns to normal, what could be wrong?

I think you mean the idle is unstable for 5-10 seconds. I have noticed this too and it is most likely to happen at warmer outside temperatures. It does not happen in freezing weather and otherwise the car runs great. Dealer thinks through-the-rail fuel injector cleaning service would help but I have already used Techron fuel additive. Our 3.0 Si has done this since new so I am guessing deposits are not the cause.

Anyone else noticed or fixed this?
