My car misses bad while it idles. I have already changed all plugs and wires and also coils. Sometimes it will idle fine for a day or two than it starts missing again.

  1. What if any check engine light codes do you have? Is the check engine light on?

    Could be a sticking fuel injector…..

    Pull all spark plugs and read the plugs, take note to which cylinder the plug came from. Look for a wet or extra black plug. This will narrow down the cylinder location and then concentrate on that cylinder only. May need to perform a compression test.

  2. Check for vacuum leaks too.
