Hi there. It does sound you have a broken timing belt. But before you immediately go out to replace the timing belt, the cover should be removed and the belt inspected to confirm that it is actually broken. Even after...

The catalytic converter may be getting overheated and turning cherry red, causing the hot floor and burning smell. The engine may be running too rich which can cause this problem as well. Also, towing the trailer can overheat the transmission....

Probably one or more electrical connections are getting wet when it rains. The wheel speed sensor for example is at wheel level (inside the wheel arch), and catches all sort of road spray. Once you find the problem connectors, spray...

Your transmission has internal issues with the solenoids or the transmission is trying to go into reverse and forward gears at the same time stalling the engine. Have each of the codes tested to see if it is internal transmission...

The information provided for your Saturn is very limited. There can be a couple of things that would cause the AC to leak into the cabin of the vehicle. A more common thing I have come across is the condensation...

If your car has a manual transmission, the some of the hard parts inside the transmission may be damaged. A manual transmission has gears, bearings, brass synchronizers, etc. Some of these are used together in certain gears and not in...

Hello. Thanks for writing in. If the noise and the light are related, then it is the rear brakes that are causing the noise. It is completely possible for an emergency brake to engage when it shouldn't. This means components...

You will need to have the exhaust inspected to see where the exhaust is leaking. Sometimes the flex pipe connected to the engine goes bad and leaks. Other times the muffle can rust through causing this. Have a muffler shop...

Most likely the Bluetooth function of your stereo is integrated into the radio unit itself. Therefore the radio itself would likely need to be replaced in order to resolve this issue unfortunately. I would recommend having the radio unit inspected...

Assuming the vehicle was running before the timing belt was replaced, I have to ask, are you sure you lined up the timing marks correctly? This would be the first thing I would check myself if I were working on...

It sounds like either the gauge itself may have failed or the sending unit for the fuel gauge that is connected to the fuel pump has failed. On most vehicles there is a floatation device that is connected to the...

A very thin film of fluid seeping from the transmission especially at higher mileage is considered normal as long as the internal fluid level is full and there are no operational problems. A thin film is considered normal, but the...

What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle...

You cannot use the remote to close a trunk after you have opened it. You will need to close it manually.

Good diagnostic work! You've narrowed it to a specific speed range, not torque sensitive, and to a specific corner of the vehicle. I suspect an "out-of-round" tire that happens to be sensitive at 38-45 mph as you note. Beyond that,...

P0304 is a "trouble code". The diagnostic fee that you are probably referring to relates to a check engine light diagnostic. The cost component in the check engine light diagnostic involved in merely downloading the "code" is trivial and, indeed,...
