After an oil change from reg. to synthetic (Mobil 1,an oil filter replacement (K&N HP-2009) and a little oil spilled on engine (no funnel!) I started the car, letting it idle for about 2 minutes and drove nearby. The first thing I noticed was the smoke from under the hood, I checked and apparently it was from the spilled oil BUT the main concern was the trembling of the car while in neutral. I also had difficulties accelerating when I switched into 2nd gear – and it felt like the engine was about to stall. This trembling and switching/acceleration problems never happened before this oil change. What could have happened? Thanks for your answers.
