    Just wanted to take a moment and acknowledge the wonderful people at this company. They’ve helped me out a number of times with quick repairs, honest work, and fair prices. They are good people and the shoot you straight every time. They make sure you understand why they are doing what they are doing and exactly what to expect. Someone give Harrison a raise. I’ve called him a number of times and he’s never failed. I’ll be a customer for years to come.

  • Just completed my first service with McCullough, and I am impressed. I have a CPO 2013 Lexus ES 350 which I have always taken to the dealership for service for the past 8 years. At 150K, I thought it was time to explore less expensive options and more convenient. I interacted with Harrison, who is a true professional and easy to communicate with. Rather than "just do the recommended service", he suggested an oil change and complimentary inspection and then determine what, if any, additional work might need to be done. There was a relatively small amount of additional work which made sense given the age and stage of my vehicle. Pricing was discussed up front and was fair. I live close so after dropping my car off, he and Daniel came to pick me up when the works was done. In this day and age of, as Clark Howard says, "non customer service", I have found McCullough to be the exception that proves Clark's rule. We will be doing more business with them and highly recommend. Adding this after another visit to McCullough NAPA in January 2025: This is my second experience with McCullough and this was just as good as the first one. Brought in my wife's car for an oil change and overall evaluation. Harrison advised we did not need on oil change...how about that, a car place advising what's in the best interest of the customer and not an opportunity to charge for another service. Harrison and team checked out the car and advised us on the vehicle, which will go a long way to our determining if we keep or trade in. The charge was fair and reasonable. We'll be back soon for a service on our other car. Keep up the good work McCullough! Went in for a third experience and Harrison was professional and helpful as always. He pointed out some items to be on the lookout for not pressuring for immediate action. Good to have a heads up for what might be coming down the road. Will back on 6 months, or mileage, for another oil change and tire rotation and overall "health" check.

    My 2012 Genesis needed a new battery, so I looked at various sources and found McCullough NAPA Auto Care reviews to be reassuring and helpful. I am very glad I went there. The lot is crammed with cars to be worked on or awaiting pickup after being serviced, but the gentleman directed me to park near the service doors after I explained my need. He immediately escorted me inside, I completed a work order, and he showed me to the waiting area. I'd say the work took maybe 30 minutes, and the service agent with whom I'd spoken on the phone about a battery, called me to the desk and handed me the keys, thanking me for coming in and directed me to my car waiting in front of the service area. Everyone was very professional, friendly, and careful to explain problems found in customer vehicles, as I overheard with several people who had come in while I was waiting. I would say, aside from friendly, honesty was my strongest impression of this family run business, and I will be back!

    This was our first repair at McCullough NAPA Auto Repair. They came highly recommended by several neighbors on the Nextdoor app. We had an excellent experience and the price was very competitive. For example, our oil change is usually around $90. and it was around $75. Eric, the owner, called with a quote for the repairs and found an issue with the oil that could have damaged the engine. I was grateful for that and decided to let them do their multi-point inspection. They found a few small issues none of which were super expensive. Then Eric, the owner, called at every milestone of the repair. He was approachable yet professional and to the point. I was always informed on the progress of their work and the car was ready quickly. I would recommend

    I’ve come here twice before and was happy with the work. But when picking my car up on the third visit I learned that my bill was more than double the price that was initially quoted to me (+$2,800 instead of $1,300), which was a substantial difference for me. The shock of learning this when pulling out my wallet to pay at the front-desk was very embarrassing to say the least! They did a good job, but my advice if you bring your vehicle here is to make sure to learn more about your quoted price. In my case, when I asked the cost, I was quoted roughly $1,300 but apparently, as my bill would show, I was only quoted the cost of “parts”. If this distinction was make known to me then I would have made an informed decision based on the price of “labor” as well.

Your Fuel System Does More Than Deliver Gas to the Engine

Your vehicle’s fuel system is responsible for storing fuel and delivering it to the engine at the correct pressure and volume. Modern fuel systems rely on several components working together, including the fuel tank, fuel pump, fuel lines, fuel filter, fuel injectors, pressure regulators or sensors, and electronic controls. A problem with any part of this process can affect how efficiently and reliably the engine operates.

Fuel Pressure and Delivery Are Critical to Engine Performance

The fuel pump moves fuel from the tank toward the engine, where the fuel injectors precisely control how much enters each cylinder. Your vehicle’s engine computer adjusts fuel delivery based on information from multiple sensors so the engine receives the proper air-to-fuel mixture for different operating conditions.

If fuel pressure becomes too low, an injector becomes restricted, or another component cannot deliver fuel as intended, combustion can be affected. The result may be hesitation, rough running, difficulty starting, reduced power, or poor fuel economy. Proper diagnosis is especially important because many of these symptoms can also be caused by ignition, air intake, or engine management problems.

Signs You May Need Fuel System Service

Fuel system problems can affect how easily your vehicle starts, accelerates, and maintains consistent engine performance. Because the fuel system contains several interconnected components, symptoms can vary depending on whether the problem involves fuel pressure, an injector, the fuel pump, a fuel line, or another part of the system. Paying attention to changes in how your vehicle runs can help identify a developing problem before it leads to a breakdown.

Common signs you may need fuel system service include:

  • Difficulty Starting the Engine – A weak fuel pump or fuel pressure problem may prevent the engine from receiving the fuel it needs during startup.
  • Hesitation During Acceleration – Inconsistent fuel delivery can cause the engine to stumble or hesitate when additional power is requested.
  • Loss of Engine Power – A restricted or failing fuel system component may prevent the engine from receiving enough fuel, particularly under acceleration or heavier loads.
  • Rough Idling or Engine Misfires – Clogged or malfunctioning fuel injectors can contribute to uneven combustion and noticeable changes in how the engine runs.
  • Decreasing Fuel Economy – Injector problems, incorrect fuel pressure, or other fuel system concerns can cause the engine to consume more fuel than normal.
  • Check Engine Light – Fuel delivery and air-fuel mixture problems can trigger diagnostic trouble codes and illuminate the check engine light.
  • Fuel Odors or Visible Leaks – The smell of gasoline or signs of leaking fuel should be taken seriously and inspected promptly.

These symptoms don’t automatically mean a fuel system component needs replacement. Ignition, air intake, emissions, and other engine management problems can produce similar symptoms, which is why proper diagnosis is important. Our ASE-certified technicians can test the appropriate systems to identify the source of the problem and recommend the service your vehicle actually needs.
