Q: Getting random misfire code.

asked by on

I have a Check Engine code for a random misfire.

Your Chrysler sets a P0300 random or multiple misfire code when more than a 1.8% misfire rate is measured during two trips. Countless issues can set this code, from a vacuum leak to a bad coil pack. Your engine is particularly prone to having this code set when the crank sensor is defective or the timing belt jumps time. However, the only way to know the root cause of the code is to have your vehicle diagnosed by a trained professional. The team at YourMechanic would be happy to help.
