Hello, looking for some help/guidance. My car is 2002, all stock with 66k miles. I owned it for about a year and it has run great until today.

I drove this morning to work with no issues. As I turn on my car to go home, it starts and idles normal. About 20 seconds later, idle feels rough and engine sounds and feels like it is rumbling and I get a flashing CEL. All I could do for now is check oil level (2 diamonds above L). I am in the process of getting a scan tool to pull code(s).

Is there anything in particular I should be looking at?

you need to see what the code is and then we can work from there.

A flashing check engine light is no joke IIRC.

DO NOT start the car.

Thanks for the replies. The codes I got are P0303 and P1399.

Danger of bore wash as <3>coil may be at fault !!!

Something as simple as a loose spark plug or bad coil can cause this.

Thanks for the replies. I changed all the spark plugs and coil 3. The old plugs were in very loose. The cars seems to be running right now.
