I am a very lucky guy because I love what I do for a living. Helping people make informed decisions about servicing their cars. Also I work with a great crew who I consider my extended family, well most of them.

Question Answered: 

It could be a couple of things. 1st thing to check is battery voltage, it should be 12.6 volts w/engine off 13.8-14.5 w/engine running. I suspect possible alternator or battery problem.

It sounds like the thermostat is stuck open. You will need to replace this first. I recommend using a thermostat from VW, not an aftermarket one. Also make sure the electric cooling fan is cycling and not just stuck as this will also lower the operating temperature.

It is the electronic version of Points. They usually fail when engine temperature gets hot, and can start to work again when it cools down again. Buy the factory replacement, you won't be sorry.

Question Answered: 

Any repair shop can use Subaru parts, and this is what I would recommend. Meineke will not use factory parts, and there is a difference in quality in terms of soud, and how long the replacement will last. I would bet the majority of the cost is the parts pricing.

Question Answered: 

These are catalytic converter below threshold faults. Four things that could cause this are; an exhaust leak, faulty oxygen sensors, a vacuum leak, and defective catalytic converters. If the converters are the cause, do yourself a favor and ONLY use factor converters because they will work, the aftermarket ones are awful. Good luck

Question Answered: 

You need three basic things for the engine to run; spark, fuel, and injector pulse. (I am assuming it does not lose compression when warm). In very basic terms, Spark and injector pulse are both controlled by a crank sensor of some kind, fuel is controlled by the fuel pump. You need to know what the fuel pressure is, not just if it has it, you need to see if the injector rapidly pulses when cranked while testing with a noid light. Then you need to see if the spark will produce 30k, usually about an inch. Ignition coil or crank sensor would be a common failure. Good luck

Question Answered: 

I think it should be a P0128 (Low Coolant temperature). If it takes the vehicle too long to achieve operating temperature, this code can set. Usually the thermostat is stuck partially opened. I recommend replacing it with a factory thermostat. I have also had oxygen sensors cause this problem as well, will need equipment to test them. Good luck

Question Answered: 

Hello Pata, here are a couple of things to check. Is there a security light flashing on the dashboard when trying to start the car? This could indicate a problem with the key of theft deterant system. Once you get the car started, will it stay started if you push down on the gas pedal? This would indicate a possible vacuum leak at idle. Look at the air cleaner for rubber lines that could have become dislodged, this is common because it is usually checked when the oil is changed. After that we need to check fuel pressure and scan for possible codes. Hope this helps

First you should check ALL the fuses, replace any that are blown. Then look at the connector at the transmission, there could be corrosion. This connector is were the reverse lights get its signal.

Question Answered: 

We need to get the fuel pressure reading and check for codes in the pcm. If there is a misfire, somtimes it will not be detected unless we perform a cylinder balance test. There is probably a rev limiter/cutoff built into the pcm that shuts down cylinders so not to damage the motor when revved in park. Backfireing could be a fuel starved engine, or cylinders not firing in the correct order. I will need some more information to guide you further.
