what causes engine to run rough

Hello, there are multiple possible causes of your running concern. My gut feeling is that you may have a fuel quality or fuel blend issue. What seems to be happening is a "hot soak" fuel concern -- meaning, fuel vaporizing before being able to be utilized by the engine. This is often due to the quality of the fuel, or a "cold weather" fuel used in warm temperatures, or a "warm weather" fuel used in cold temperatures. Did you know that there are something like 6 different fuel blends used during different times of the year, depending on many factors including on your climate? I would also have a fuel pressure test performed on your vehicle. Fuel pressure concerns could also cause this.

Could be a bad coil, bad crank sensor, a vacuum leak. It's hard to tell without looking at the car and using a scanner to check actual values when the issues is happening. This will require a hands-on inspection or you're just guessing. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex
