Don't Just Change Parts - Diagnose It!

Have you ever went to a mechanic who told you such and such part is the source of your engine's problem, only to have that part changed and the problem not go away?  Then be told another part needed to be changed and the problem still not go away?  And so on and so on?

The way most garages in Jerusalem ( and elsewhere ) operate is that they diagnose based on symptoms and experience. What does that mean? It means that over time, they've learned that “most of the time” a particular symptom is caused by the failure of component X, or Y, or Z in that order of probability. After a cursory inspection, they say to replace X, then when that doesn't work they replace Y, and then Z. They lack either the tools, knowledge, motivation ( or all three ) to arrive at a precise automotive diagnosis.

A perfect example of this is a customer complaint of low power, poor fuel efficiency and rough idle. The first thing many garages in Jerusalem ( and elsewhere ) will recommend is to change the spark plugs and ignition wires. If that doesn't work then it's the ignition coil ( or coils ) next. Then an “infusion” where the intake manifold and valves are cleaned. And so on and so forth until either they get lucky or you give up.

Here's a list of the most common causes of these symptoms. In addition to the above and in no particular order:

  1. Cracked or torn air hoses causing a vacuum leak

  2. Defective IAC ( Idle Air Control ) Unit

  3. Defective Lambda / Oxygen Sensor

  4. Poor fuel pressure

  5. Clogged fuel injectors

  6. A worn out cap and rotor on a distributor

  7. Defective crankshaft or camshaft position sensors

  8. A jumped timing belt

  9. Poor compression in one or more cylinders

  10. Oil leaking into the spark plug wells from a defective valve cover gasket

  11. Defective Ignition Control Module

  12. Defective wiring

  13. Malfunctioning Clutch on the Alternator or A/C compressor

  14. Malfunctioning Engine Computer

  15. Dirty or defective MAF or MAP sensors

And this isn't an exhaustive list.

At Shriver Mobile Automotive Diagnostics we specialize in computerized, scientific, and precise diagnosis. We're a type of mobile garage in Jerusalem that specializes in diagnostics.

For most cars sold in Israel since 2003, and for select vehicles as far back as 1989, we can connect directly to the car's engine computer to aid in our diagnosis.  But we don't stop there.  In order to verify with near 100% certainty many electrical and mechanical problems we use an automotive oscilloscope to directly read the electrical signals from the various sensors and components in the car.  Those tools, together with scientific reasoning and a deep understanding of the electrical and mechanical principles that the engine operates on allows us to arrive at a diagnosis with an extremely high level of confidence.

Our price for a diagnosis is a flat rate of 75 NIS if you come to our location in Kiryat Yovel, or we can come to you for between 100 to 150 NIS depending on driving distance.  Don't have your car towed when we can diagnosis it where it's parked.

We can also help with the import of small parts such as sensors and ignition coils, which usually can only be bought at dealerships and are typically extremely expensive.  We can typically import them for less than 1/2 of the local price, including shipping and our 100 NIS fee.  In most cases, they can be installed for free.  We have a detailed parts catalog for all cars sold in Israel with OEM part numbers, so you don't have to worry about accidentally ordering the wrong part.

The price of an accurate automotive diagnosis in Jerusalem is usually far less than the guess and replace parts approach. Try us out!
