I took my car to a mechanic because the check engine light was on. The codes he got when he did a reading were P0420, P0304, & P0300. He did an inspection and found that I need all catalytic converters replaced, oxygen sensors, spark plugs & ignition coil. I'm taking my car to be repaired and most likely will have to go to two different shops. Which repair should I get done first? The catalytic converters/oxygen sensors replaced OR the spark plugs/ignition coil?
have the same problem?
