I’ve had this problem for a while now. When my car is warmed up, and I’m at a stop light or just idle when parked, the engine struggles to stay on. The RPM stays under 1000 and fluctuates a lot, usually between 500 and 700. It’s stalled few times, but mostly it is annoying.
I read around and decided to replace the fuel filter. Been two days, but so far no change. I will try the oil filter next, but I was hoping someone could give me advice on the most likely culprits so I can try and at least diagnose it and go from there. Oh, and there are no check engine codes. Everything checks out so far.
