He invests in training his staff and provides them with the automotive tools and computer diagnostic equipment needed to get the job done right.

Toyota Spark Plug Replacement Details

The spark plug uses the energy produced by the ignition coil to generate the spark necessary to ignite the air/fuel mixture in the combustion chamber.

Common Symptoms:

  • Check Engine Light may come on or blink
  • Engine may run roughly
  • Abnormal engine noise due to loose or missing spark plug

What the Mechanic Should Do:

  • Failing spark plugs can cause the engine to run rough and misfire, which can trigger the Check Engine Light. Continuing to drive under these conditions can damage the catalytic converter.
  • Engines may have one or two spark plugs per cylinder and each spark plug can have from one to four electrodes
  • Replacing spark plugs can be labor intensive on some late model vehicles
  • To prevent ignition misfires and Check Engine Light problems, we recommend using only high-quality spark plugs, and preferably spark plugs from the OEM
  • Spark plugs have different ratings and it's important that the correct type are used
  • Spark plug terminals wear down over time and can lead to engine misfires. At a minimum, they need to be replaced at the mileage specified by the vehicle manufacturer.
  • Manufacturer's instructions should be followed when removing spark plugs. Cylinder heads made from aluminum can be damaged if the correct procedures are not followed.

I had my brakes done at the shop. The Nissan dealer tried to over charge me and tell me both axle needed to be done. My Mechanic quoted me fair price and let me know my rear axle was fine. My front rotors got machined and the brakes feel good.

Easy to get quick appointment to get work done, completed as promised, and reasonably priced.

They listened to my concern and scheduled a time to receive and inspect my truck. After the inspection, they called and discussed the issue. We agreed upon a solution that was very reasonable in price, and they completed the work quickly and efficiently. They also provided an easy-to-read analysis of the health of the vehicle including some other potential service items. One point to mention is that they specifically did not complete a work request I had made because it would not have yielded satisfactory results without other work I was not prepared to do. This reduced the cost of the service, and allowed me to save money to complete the rest of the work I need to get done at a later date. I find this shop trustworthy and competent.

Drop off 2009 Audi Q5 for oil service and engine valve gaskets replacement. Later that same evening I noticed a pool of coolant in the garage and a trail of coolant as my wife pulled out of the garage. After further inspection, I found that the hose that attaches to the coolant reservoir has not put back correctly causing the major spillage/leak. Email the shop to let them know of the situation but never got a response back. We felt like our problem got ignored and wasn't a concern to them. We are not people that like to complain but wanted to raise the issue with them to maybe get a call for a visual inspection. But nothing. We will not be bringing our cars back here for service even though it is convention for us to.

Managers and Tech were very informative and made appropriate recommendations based on my vehicle and my needs. They gave insight into what they have seen in their experience with similar vehicles. They were efficient and fast.

This was the second time I had taken my car to My Mechanic. As before, the service was exceptional. Very professional and friendly customer service, repairs were made same day, and the cost was extremely reasonable.

You guys made a great diagnosis. Thanks for great service! And cutting me a bit of slack for the Jeep I need to donate.

Brought my car in to repair the Air conditioning. Needed to replace the compressor and AC belt. Work was done within a day and had fantastic service as usual from Warren and his team. The AC works fine now.

Very professional and knowledgeable repair shop. Friendly service and they don't try to upsell you repairs or services that are not needed.

I wouldn't dream of taking my vehicle anywhere else but here. Warren and Co. are hands down the best! I'm very proud to call them, "My Mechanic".

by - Verified Customer July 01, 2016

They seem honest! I was afraid my car would need extensive repair after the engine hesitated and the check engine light started flashing. They checked it out and originally said that the ignition coils were very worn and the spark plugs were a little worn, so they'd replace all of that, but then they checked the spark plugs once more and decided that replacing them wasn't necessary and that I could still get a lot of use out of them, saving me around $150. According to the OpenBay app they charged me a fair price for the repairs. The car has run like a dream since, and a few more of its quirks vanished (it's old).

The work was performed in a timely manner, and they didn't press any additional work which I appreciated.

by - Verified Customer June 21, 2016

Dropped off my car at My Mechanics on my way to work for an oil change and routine service, as well as to inspect squealing front brakes. They identified the cause and called to recommend new front brake pads and discs. Service was completed promptly, and I was able to pick up my car after getting off of work. They also unclogged one of my windshield wiper spray nozzles. Fantastic, friendly service as usual.

by - Verified Customer June 21, 2016

I have gone to My Mechanic for anything that has happened to my car for the past 3 years. They are the best that have ever worked on my car. They are great to work with, very accommodating, and fairly priced. I will always go to them with any problem with my car.

by - Verified Customer June 20, 2016

My Sprinter cargo van was serviced. Outstanding. Will need to bring Van in to have tires replaced. Warren is top notch as always. This service was difficult due to the size of the van.

They were great. On time, stuck with the quote and didn't add on "extras". Very pleased. Nice to have a local shop I can trust.

by April 26, 2016

Great service. Clear on what needed to be repaired. Expensive, but that was expected. They went out of their way to offer me coupons for the tires which was awesome.

by - Verified Customer April 13, 2016

This shop bent over backward to not only take my car the same day I called but in working with the dealer to get some parts and programming instructions specific to my vehicle. They stayed in communication with my the entire time so I knew exactly what was happening with my car and did not charge me an arm and a leg. They fixed the problem amazingly and do excellent work.
