Richard

The part had not yet arrived on the day of service and Richard called me first thing in the morning to let me know. He kept in touch with me and was on the lookout for the part. He arrived only 30 min after the appointment time with the part! He quickly installed my fuel pump and was on his way. I later found out there was another issue with the car, which hadn't been diagnosed before (he had not done the initial diagnosis) and he quickly came back out to take a look at it. Throughout the process Richard has been polite and understanding.

Great mechanic!! He gave my car a good inspection and found some additional things I should take care of before they cause bigger issues. Did my original service quickly and effectively (and might I add this guy is very prompt). Will definitely book with Alfredo again.

All about Spark Plug Replacement

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.
