Possible Answers

If there are no signs, the easiest thing to do is to reset the code and see if it comes back. If there are signs such as that the engine is failing or slowing down, look for all connectors and connectors that lead to the plugs (eg plugs). Depending on the length of time you spend on car accessories, it may be best to adjust them as part of your maintenance plan. I recommend plugs, plug wires, split cups, and rounds (if possible). Otherwise, look for coils (aka coil packs). In some cases, the support switch has gone wrong. If you are smelling hot eggs, your cat converter should be changed. I have also heard from time to time that the problem was with the wrong fuel.
