Engine Diagnostics Done Right in Princeton, NJ

A check engine light can point to a dozen different things, and pulling the code is only the first step. The code tells you what system flagged an issue. It does not tell you which part failed, why it failed, or what actually needs to be replaced. At Tiger Garage on Witherspoon Street in Princeton, we read the codes and then do the diagnostic work to trace the problem to its source. That distinction matters, and it's the difference between fixing your car and spending money on parts that weren't the problem.

One customer came in with a Service Engine Soon light, delayed automatic shifting, and a car that suddenly jumped into neutral at highway speeds with the tachometer climbing past 8,000 RPM. Within an hour, we had pulled the codes, traced the fault to a bad speed sensor giving erratic signals, sourced the replacement part, and had the car ready to drive in under four hours. That's the kind of diagnosis that saves you from a much bigger repair bill somewhere else.

We handle a wide range of engine work: head gaskets, timing components, valve cover gaskets, oxygen sensors, fuel system repairs, and more. We've replaced head gaskets on Subarus, done engine repairs where a dealer quoted $5,000 and we came in at $3,200, and sorted out complex sensor faults the same day they came in. If your engine is running rough, losing power, burning oil, or throwing codes, we'll find out what's actually going on. We tell you what we found in plain terms, give you the cost before we start, and don't add anything to the invoice you didn't approve.

ASE-certified work backs everything we do. Troy and the team at Tiger Garage have been working on these vehicles long enough to know what breaks and when, and we're not going to recommend a head gasket replacement when a sensor is the real issue.
