So recently I've noticed that at low fuel loads that my idle is much more unsteady and even feels like it is going to die at times. Tonight when I drove briefly, the car felt fine when I was accelerating and using the throttle in general. But the car sounds like dog poo at idle. The sound was directly related to the cars idle being unsteady and trying to die as they both happened at the same time.
Also, sometimes when I am accelerating the car feels like the power is "swimming" kind of like a sin wave.
Thus far, I have never seen a check engine light or any electronic indication that anything is wrong; just what I have seen, felt, heard from the car.
I wanted to see what others thought about these things. I took a couple videos, and I may post them later, but I think most of the sound is washed out on my poor cell phone microphone.
If all else fails, does anyone know a reliable and trustworthy repair shop in the Austin area of Texas?
