car shakes at idle and is fine during acceleration..
So my daily driver the other day started shaking when I was at a stop light, the cel light way blinking, but I was only 4 blocks from home so I went back. During acceleration, the car doesnt shake but at idle it does. I went to go see what was wrong today and when I started it, the cel light way just went on and wasn't blinking anymore, but the car still had to same problem. The car is a Hyundai i-4 engine. I was going to pull each spark plug one at a time, but I dont have any tools with me because I'm at college and the valve cover has a lot of bolts. I'm going to be looking for a set of tools to borrow tomorrow, but just wanted to get some thoughts before I started.
