Engine Repair & Diagnostics in Princeton, NJ

Check Engine Light? Let's Find Out What's Actually Wrong.

When your check engine light comes on, the car's computer has logged a fault code. What that code tells you is which system triggered the alert. What it doesn't tell you is exactly which component failed or why. A lot of shops skip past that step and just replace whatever part the code points toward. At Tiger Garage, we do the actual diagnostic work first.

We've seen this pay off for customers time and again. One Infiniti owner came in on a Monday morning with a Service Engine Soon light, delayed shifting, and a transmission that had lurched itself into neutral while driving. We pulled the codes, traced the fault to a faulty speed sensor sending bad signals to the transmission control module, sourced the part, and had the car back on the road within four hours of arrival. That's the kind of result you get when someone actually diagnoses the problem instead of guessing at it.

Tiger Garage on Witherspoon Street works on all makes and models, including the European and Asian vehicles that some independent shops wave off. Whether it's a twenty-year-old high-mileage car with a check engine light or a newer vehicle with complex electronics behaving strangely, we go through it the same way: identify the fault, confirm the cause, tell you what it will cost to fix, and wait for your go-ahead before starting. One customer brought in a 20-year-old car expecting a long repair list and got a same-day turnaround with a clear explanation for every charge. That's the standard we hold ourselves to. Our ASE Certified mechanics handle everything from minor sensor faults to significant internal engine work, and you'll always know what you're paying for before any parts get ordered.

Engine repairs are the kind of job where you really want the shop to get the diagnosis right the first time. If we find that something doesn't need to be replaced, we'll tell you that. If it does need work, we explain what, why, and what the consequences are if you wait. No pressure, just the information you need to make a good call.
