Why Are My RPMs High at Idle?
The Problem
The vehicle owner noticed that the RPMs would go high when the vehicle was idling or driving.
What We Found
The technician conducted a smoke machine emissions test and found issues with the PCV valve and intake manifold gaskets.
The Fix
The team replaced the faulty PCV valve and hose, as well as the intake manifold gaskets, including the valve cover gaskets. They also performed a complete coolant system flush to address acidic coolant that could damage the water pump, radiator, and thermostat.
The Result
After the repairs, the vehicle operated smoothly with normal RPM levels during idle and driving.
Pro Tip
High RPMs at idle often point to issues with the PCV valve or intake gaskets. Addressing these promptly can prevent more severe engine problems and maintain optimal performance.

What Does a Complete Coolant System Flush Involve?
The Problem
The vehicle owner came in for a routine oil change and mentioned concerns about potential maintenance needs.
What We Found
During the inspection, the technician noted that the coolant was acidic, which could damage the water pump, radiator, and thermostat.
The Fix
The team at our Frostproof shop performed a BG Complete Coolant System Flush. They used a BG machine to withdraw and flush out all fluids from the engine and radiator, then refreshed the system with new fluid to ensure optimal performance and longevity.
The Result
The vehicle left the shop with a refreshed coolant system, reducing the risk of future damage to key components.
Pro Tip
Coolant that turns acidic can damage your engine's water pump and radiator. Flushing and replacing it every 30,000 miles helps prevent costly repairs and keeps your engine running smoothly.

Why Is My Check Engine Light Flashing with a Misfire?
The Problem
The vehicle owner experienced a worsening misfire, even after replacing the coils, accompanied by a flashing check engine light.
What We Found
The technician found that the throttle body was dirty, which can affect the engine's air-fuel mixture and lead to misfires.
The Fix
The team performed a scheduled tune-up for the 4-cylinder engine, which included a comprehensive fuel injection cleaning. They also cleaned and serviced the throttle body to ensure optimal engine performance.
The Result
After the service, the misfire was resolved, and the check engine light was no longer flashing.
Pro Tip
A flashing check engine light often indicates a serious issue like a misfire. Addressing it promptly with a tune-up and throttle body cleaning can prevent further engine damage and costly repairs.

What Causes Brake Fluid to Darken and Absorb Moisture?
The Problem
The vehicle owner requested a full oil change service.
What We Found
During the inspection, the technician found that the brake fluid was dark and had absorbed moisture, which is not ideal as the fluid should be clear.
The Fix
The technician performed a BG Brake Fluid Service by flushing the brake system reservoir and lines, replacing the old fluid with new, clear brake fluid. The reservoir area was also cleaned to ensure optimal performance.
The Result
The brake fluid was restored to its proper condition, improving the vehicle's braking performance.
Pro Tip
Brake fluid should be clear. If it appears dark, it's likely absorbing moisture, which can reduce braking efficiency. Consider a brake fluid service every 30,000 miles to maintain optimal performance.
What Frostproof customers say about our preventive maintenance work
The BEST experience I have ever had with a car repair shop! Their customer service exceeded all expectations from the time I came in to explain my issues with my vehicle, to the timing of the inspection, and the estimate. They were ALL super friendly and professional! I would HIGHLY recommend this place to anyone in need of auto care because, they DO care! Oh, and I cannot forget the red roses in my steering wheel...nice touch, Johnny's!!! 😃

The guys Jeff and his assistant are wonderful. They are very knowledgeable and kept us informed of what was needed for our vehicle. We really felt like they cared about our car and treated us with respect as valued customers. They kept us informed of the status of our car without having to chase them down like at other mechanic/repair shops. In addition, Jeff and his staff even gave us a loaner car until the repairs were completed on our car. We will definitely come back for maintenance and any time we have car issues. This shop has been around for six years and is clean, have rest rooms, and snacks for their customers( which my husband loves to indulge ever time we visit). WE HIGHLY RECOMMEND BRINGING YOUR VEHICLE HERE!

I used Johnny’s for my pre-purchase inspection on a used vehicle. Ron was incredibly kind and helpful, shared expertise on how to best maintain my car, and was a pleasure to work with.

Took my car to Johnny’s for regular maintenance, they were thorough, reasonable, and quick. Jeff was amazing, customer service was great, the facility is clean and not like any other shop I’ve been to. Highly recommended!

Very trustworthy. Prices are equal to or slightly less than what I would pay for the same maintenance or repair service at a dealership. However, the positive difference in the attitude of their customer people, and their efficient and immaculate business environment, their customer service amenities in the waiting room, and the overall verifiable, concrete evidence of a strong customer focus ethic - all go together to make Johnny's my maintenance and repair shop of choice, whether it is my 13-year-old car, or my 2-year-old's car. They make what could potentially be a very unpleasant experience, just the opposite. Kudos to the manager and all those who work there, from the mechanics to the customer service desk. Excellent place, staffed by people who take excellence seriously.

Preventive Maintenance in Frostproof: questions answered
Answered by our licensed technicians serving Frostproof.
How do I know what my car actually needs right now?
Give us the year, make, model, and mileage and we'll pull up the schedule your manufacturer published for that car. That tells us what's due by the book. The digital inspection tells us the rest, because a photo of your actual filter or fluid beats a guess every time.
Do I have to go to the dealer to keep my factory warranty?
No. You can have your scheduled maintenance done at an independent shop like ours without giving up your factory warranty. What matters is that the work follows the manufacturer's schedule and that you keep the records. We document what we did, when, and at what mileage, so you have the paperwork if anyone ever asks for it.
What is severe service, and does Florida driving count?
Most owner's manuals list two schedules, normal and severe. Severe covers short trips, stop and go traffic, heat, dust, and towing, and a lot of Central Florida driving lands in that column. It doesn't move every interval up, but it does move a few, and we'll point out which ones apply to how you actually drive.
Can you set up a maintenance schedule for me?
Yes. We'll build it off your manufacturer's intervals and how you use the car, then keep it in your file so each visit picks up where the last one left off. You'll know what's coming next and roughly when, instead of finding out at the counter.
What happens if you find something during a maintenance visit?
We photograph it, send it to your phone, and tell you whether it needs doing now or can wait. Plenty of things can wait, and we'd rather say that than sell you a service you don't need yet. Nothing gets done without you saying yes to it first.
