Wierd Idle on Startup......

[Hibrydsoul]

Okay so for my next "for real" post, I'm getting a wierd idle on startup. This will happen when the engine is cold. As the engine starts..... it throttles as though it it wants to cut off..... and would eventually sort itself out and idle properly a few seconds after. I never experienced this only until I added Premium into the tank. I'm pondering that my injectors may need cleaning. It shouldn't be the fuel filter as it was recently changed about a month now. So my uneducated guess is the injectors?

so if u put ur foot on the gas does it smoothen out or does it break up an cut off? does it idle normally after its warmed up? this is on a 4efte motor right?

That issue apparently was caused by switching to Premium. As soon as I switched back to super, it resumed idling normal, so no worries there.
