Check-engine
diagnostics
The light is on. That does not mean you need a $1,200 sensor. We scan the car, confirm the fault, and tell you in plain English what it is and what it costs before anything gets touched.

Check-engine and warning lights
Scan, freeze-frame data, and a live test so we are not guessing from a code printout.
Misfires, stalling, and no-starts
Ignition, fuel, and sensor faults isolated on the bay, not by parts-cannon.
Emissions and inspection fails
Bring the fail report. We chase the code that failed you, not a shopping list.
Electrical gremlins
Intermittent lights, battery drain, and modules that throw codes they did not earn.
Sound familiar?
Check-engine light just came on
Could be a loose cap. Could be a misfire eating a catalytic converter. A scan tells us which before you drive another week on it.
Light is flashing
That is an active misfire. Park it and call. Driving it like that is how a coil job turns into a converter job.
It runs rough or stalls
Fuel, spark, or air. Ten extra minutes of testing here saves you from replacing the wrong part twice.
Failed NJ inspection
Bring the sheet. We fix the item on it, quote it first, and get you back in line for a retest.
Free computer diagnostic scan
With a qualifying repair. Additional diagnostic labor may be required depending on the concern.

FAQ — DIAGNOSTICSIs the diagnostic scan free?
New customers get a free computer diagnostic scan with a qualifying repair. Extra diagnostic labor can apply on deeper faults. We tell you that before we go looking.
Can you just tell me the code?
Yes, and then we test it. A code is a starting point, not a parts list. That is how people end up buying an O2 sensor for a wiring problem.
How long does a scan take?
A straightforward check-engine scan is usually same-day. If the truck has to pick the car up in Hillside or Elizabeth first, say so when you call.
Do I need an appointment?
Call ahead and we will hold a bay. If the light just came on and you are already in Union, swing by and we will fit you into the queue.
