Symptoms: The car seems like it's running down one cylinder. I was driving home two weeks ago and all of the sudden the car started missing and surging at a stop light. A blip of the throttle is followed by a dip in rpm to the point where it feels like it's going to die, then a surge in rpm. Under acceleration, the engine runs smoother, but seems down on power.
I tried to trouble shoot it today. Cold start it was having trouble immediately. The idle surged and dipped from cold start almost like a vacuum leak. After some warm up, the idle would settle but it was high and a little rough like a miss. I noticed there are time where it sounds like one of the injectors is emitting a high pitched beep/squeak.
No DTC codes at all.
I am thinking maybe an injector based on the noise i was hearing? Anyone else ever experience that?
