One of the most important tools we have when we are diagnosing an intermitent problem is the Diagnostic Worksheet.

Diagnostic Worksheets

One of the most helpful tools we have when diagnosing an intermittent problem is the Diagnostic Worksheet. It is vital to a speedy and less costly diagnosis. The diagnostic worksheet can be filled out by you or by our staff, either way it establishes a good baseline for us to work with.

With good quality relevant information gathered by you about the specific issue, it will help us to understand the problem more clearly and allow us to zoom in on the root cause of that problem more effectively saving us time and you money in diagnostic costs.

It is very important when having something diagnosed to not jump to conclusions or give us a list of conclusions you have found on the Internet or a list from a friend, please only list information and symptoms that you are “actually” experiencing -- this information will help us the most.

Simply download the appropriate diagnostic worksheet, describe what you are experiencing and bring it with you in order to assist in the repair. This will help us to understand, in greater detail, the nature of your vehicle’s problem thereby speeding repairs and reducing costs.

Whether it is an easy fix or a complicated diagnoses we can help, and understanding the diagnoses process and related costs and expectations is equally important. Our goal is to help you through this process in the most economical way possible, while still maintaining a quality diagnoses and repair.

Whether your check engine light is on or off you could be experiencing an intermittent issue that comes and goes and it simply drives you nuts. Rest assured intermittent problems drive us nuts too. So, this seems like a good time to discuss "intermittent" issues.

Intermittent issues are the most challenging to diagnose, they also present a very challenging situation between the shop and customer because the expectation of the customer is to solve this issue that's driving them nuts, however the problem is not surfacing, and here's where the trouble starts, we set-up testing equipment, recreate the circumstance in an attempt to experience this intermittent issue and it does not "act" up.

After several attempts, still no sign of the issue. We call you or most times you call us for an update and we have nothing!!! That's not to say that we do not have results of testing performed, it is that we simply have NOT experienced the concern, thus no solution to the problem.

This news is never welcoming for either party, as it extends and complicates the situation. You want the problem solved and we want to solve it, however the problem is simply NOT showing up. Hours, sometime days pass by, and you are wondering about your car, and we are wondering if we can every get this problem to show up so we can help you solve it, but to no avail, it is a no show!

What do we do now? You want your car, and your car back fixed, as we do, but no problem found! With this wonderful news you are anxious to pick-up your car, pay the diagnostic fee and hope for the best and most certainly praising us for our inability to solve the problem and charging you for that inability.

We have soured more customer relationships due to intermittent problems than any other thing, however with a whole lot of patience, perseverance, and utilizing tools like the diagnostic worksheets to assist us in the process we can assist you in a more timely and accurate repair.

To learn more call us at 909-346-0444 or simply stop by and we can discuss your diagnostic needs. We always offer FREE Computer Scanning and Advice on 1996 and newer vehicles. Therefore, if your Check Engine light is ON we can help you find out what codes are stored and suggestions on repairs that may be needed.

However, in most cases you'll need to consider more in-depth diagnoses and testing to confirm the root cause of the problem(s) and to understand what repair(s) are necessary, or if additional diagnostic time is needed for situations where there are multiple codes, potential causes and/or to gain access to a component(s) for higher level testing. Either way we can help.

"Awesome Service! Been coming to the Care Shop for a few years. They always do great work at reasonable prices. Very honest when needing repairs, never try to sell you more than you need. Mark & Rose are really nice people and have great customer service skills."
Roger M.
"Mark & Rose & co. are just the best in taking care of my car. Mark takes the time to explain what they do, the mechanical aspect, and give me the lowdown if I need to be worried or not. And their prices are reasonable for the through attention they give to my car."
James S.
"My '05 Honda had a bad vibration under acceleration. Mark narrowed it down to ether the transmission or a half shaft. He was reluctant to fix both because of the cost I would incurre. I feel other mechanics wouldn't care and charge me for the biggest profit. Mark replaced the half shaft and problem solved."
Federico C.
"Always Professional and reasonable. The staff at the Care Shop always answer my questions and are extremely fair in providing my professional service at a reasonable rate."
Bob E.
"The Top Shop. A clean organized shop is a pretty good indicator of the operation. Honest, great communication, excellent work, on-time completion of work as promised and most of all, reasonable $$$."
Loren R.
"Always great service! The Care Shop always provides just what I need in a timely manner. The shop staff and the office staff (Mark and Rose) are great people and fun to be associated with."
Ray K.
"This place did a great job on my old truck. The recommended services were done at a reasonable price and the truck was done when promised. They pickup the phone when you call and have excellent customer service."
Craig B.
"Quality and Honesty exemplified. I find them extremely honest, they diagnosed a problem they thought it was, and then the next morning called me back saying they woke up early and thought about it and it was actually a less pricey issue to fix. I appreciated this because it was a tricky issue, and the initial one would have been costlier, so he was extremely honest. I've recommended them to many people so far."
