Very rough idle and difficulty cranking.

Car was running at normal temp and when I got home and checked the mail my car started idling really bad. Jumping all over the place. Parked it for a minute and when I went to crank it back up it took about 3-4 seconds to crank. Just replaced spark plugs roughly 3 weeks ago (with the correct ones) and changed oil over a week ago. No check engine light is coming on and I have no clue what to do. Everything looks fine but car is running bad. Just filled up 2 nights ago and have been getting normal gas mileage so I don't think it's bad gas but I could be wrong. I'm about to lose my mind lol

what kind of gas you use? regular or premium? also check for EGR valve has carbon deposit in it. Your symptom looks like carbon has block the EGR valve housing.

I've used premium since I've had the car. I'll check the EGR.

Carb cleaner or brakes cleaner will do the job.
