Hello. If the idle is that low, then it can be caused by a number of things. Most of the time it is caused by a vacuum leak or a dirty throttle body. The throttle body being the most common....
The noise is coming from the internal transmission bearing or overriding clutches. Not all of these parts may have been replaced when the transmission was overhauled. I can only recommend having a qualified transmission mechanic come and listen to...
The shaking and stalling out as you describe can be caused by a variety of issues. When this happens there is likely a Check Engine Light on that should register a fault code in the car's computer. I would recommend...
Depending on the reasoning for replacing the fuel pump, it may be that there are additional issues with maintaining fuel pressure such as a bad fuel pressure regulator. The fuel pressure regulator is a device which controls the pressure of...
Hi There, Unfortunately, it sounds like the shift linkage may have been broken during the tow. This can happen when the car is jammed into gear or forced from one gear to the next. The will not come out of...
The scraping noise was the timing belt rubbing on the timing cover. The issue could be the timing belt may have jumped a tooth. This will cause the engine to have a no start condition. Check the timing on the...
Hi there. It definitely sounds like something is shorted electrically and not only draining the battery, but also preventing the proper operation of the other electrical components in the vehicle. This is a serious draw on the electrical system and...
Normally, if there is a hydraulic leak that lets the brake pedal go to the floor, the condition remains until its repaired. with your brakes coming back as you describe, it's hard to say what occurred without knowing more of...
Hello. If the exhaust system is original, that is if it is about 20 years old, you will probably end up replacing the entire system, consisting of the "Y" pipe coming off the manifolds, the converter, muffler, and tail pipe....
This may mean you are running too rich and will need to have the engine O2 sensor and mass air flow checked to see if they are causing the engine to run too rich. i recommend having a mechanic like...
Many different parts can cause the vehicle to overheat. The most common would be the thermostat, radiator, water pump, air in the coolant, or a coolant leak. When a vehicle overheats at idle the usual suspect is the radiator fans....
Hi there - you can certainly have a blown head gasket without a lot of dramatics - at least initially. If the white smoke from the exhaust has a sweet smell to it, that's a good indication that the head...
For me, the Honda is a better quality vehicle. But you are comparing vehicles that are 10 years apart. If the price is the same, then I would get the newer vehicle if it is in better shape. If you...
Hi there. I see your question is about a Volvo HF7 even when you clicked the Toyota Avalon buttons - I'm will be answering this question as it is associated to the Volvo HF7 vehicle provided. Check the battery cables...
Hi there. Thanks for contacting us today. If you shifted into reverse while the vehicle was in forwarding motion, it's likely that shift linkage or the reverse gear itself has been damaged. Honestly, without completing an inspection, it's hard to...
In many cases, the symptoms you're describing are related to a blockage in the fuel delivery system; perhaps the fuel injectors or the throttle body itself. Over time, carbon builds up inside the throttle body and the [fuel injectors]((https://www.yourmechanic.com/article/what-causes-fuel-injectors-to-get-clogged-or-dirty) which...
Over a period of 20+ years, the internal engine components begin to fail. When it comes to blowing smoke and rapidly losing oil level, typically there are two culprits; the valve guides in the cylinder head, and piston rings inside...
Hello. It sounds like you may have a bad vent or purge valve in the evaporative emissions system. Most of the time this is caused by the purge valve. These valves work to contain the gas fumes in the vehicle...
If you are losing that much oil, and there are no external leaks (leaks that are visible outside), your vehicle may be consuming the oil. Unfortunately this can be harder to diagnose than an external leak. The valve guides and...
Hi there. It appears that the issues you're experiencing may be caused by the ignition lock cylinder. In some newer vehicles (made after 2000) this part has multiple springs inside the cylinder that allows you to press the key forward...
I would first check to see if your Check Engine Light is illuminated. If so, there are likely trouble codes that have been stored in your vehicle's PCM that may indicate what the problem is. In order to pull these...
