Mobile auto repair is a really smart business idea. It sounds like your customers really trust you! How long have you been doing this?

You should check the condition of the spark plug to see if it's worn out and to see if any possible carbon tracking. If nothing is found within the ignition system further diagnosis will be needed. Many things can cause a P0303 cylinder misfire, but the ignition system is the easiest and simplest to check first. Also, depending what is causing the misfire there could be a possibility of bad electrical wiring/computers so you have to check everything. You will have to analyze the data on a scan tool to see what is happening. The next thing you could check is the fuel system such as the fuel injectors, etc. In some other cases there could be a mechanical problem related to poor compression such as a bad intake/exhaust valve, piston rings, etc.
