Wow mine is doing the same thing. Mechanic changed one mount and now the vibration is worse. It's like really rough now. I have already had the throttle body cleaned as well a couple times. We serviced the transmission and I was just wondering what it was. Will have to find out about the exhaust hanger things!

I think the problem is, one or both of your battery leads are not connected properly. You need to do two things when you installed the new battery. Ensure the leads are completely clean of any type of debris or corrosion. Second, ensure they are tight enough to have a proper and secure connection. I believe the Concorde has side posts on the battery. These ...

The sound of the clicking is from the starter relay. There is a little bi-metal strip inside of the plastic housing and it's flapping back and forth. It's the same concept as a turn signal, it's just happening more rapidly. It means the voltage on your battery is low. Even though you just drove it, it might not be holding a charge well. Very hot ...

My first question is: is the mid point at 90 degrees the optimal temperature for the car to be running at. Or the max temperature where the cooling decides to work harder and bring it down if it goes over? Or is this the same thing? The system is designed to run more or less in the middle. Most gasoline cars are around 90-100 degrees Celsius. The ...

My suspicions would lean more towards debris left in the block. Most salvage yards by their nature are not particularly clean. My thoughts would a rodent nest or other debris. Another possibility is not a clog but an air pocket that has settled in the heater core. If you check this site for no heat links you may find some info on determining how to resolve ...

You may be able to get close to what you want by installing a stainless steel exhaust (as opposed to the standard mild steel). It will give you a more raspy sound. In addition, deleting the center resonator/muffler and adding a freeflowing sports rear box with a large tip (diameter should be larger than the diameter of the pipe coming from the cat) would ...

What your ears may be detecting is the camshaft specifications. In the sixties the flat tappet camshafts were the norm. To get a better picture on how a camshaft works look up "how stuff works/camshaft. Looking at the cam spec graph you will see there is a time when the exhaust valve is not fully closed and the intake valve is on its way open. This is the ...

My best bet is that the spark plug is too long in the first place. I don't know what the stock spark plug should be for your bike, but the NGK you are showing may/may not be completely within spec and therefor is extending down into the cylinder longer than the spark plug should. If the bottom end was worn out enough to allow the piston to travel that far up ...

To run, an engine needs 3 things - the correct fuel/air mixture, compression, and spark. If any of those are missing, it won't start. When you try to start it, does it sound like it normally would (i.e. not turning significantly faster or slower than a normal start)? Does it have enough of the right sort of fuel? (sounds like a silly question, but you'd ...

There are advantages, but also disadvantages to using a smaller turbocharged engine with a higher power output. The pro's of smaller, turbocharged engines: When not on boost (below e.g. 3000RPM) the engine uses much less fuel. turbocharged engines have a flatter torque curve, meaning they're working closer to optimal level throughout a larger portion of ...

In addition to size, weight and fuel economy, a small, highly tuned engine is going to be much more ecologically friendly. This is because a large engine producing 350 bhp can do it without being highly tuned - fuel is unlikely to be fully burned, emissions will be higher than with a smaller engine which can burn fuel more fully.

There are several advantages to a lower displacement engine over a larger one. Firstly is weight, an engine of 2,000cc will weigh significantly less than a 3,000cc engine because it will have a smaller block, this in turn decreases inertia of moving parts (such as the cylinder head and cam shaft). Secondly we can factor in fuel economy, if an engine has ...

Your Golf should have two fuel pumps: one for the injectors (high pressure) and one which feeds the injector pump (low pressure). The low pressure pump would reside in the fuel tank. I'm thinking the low pressure pump may be going bad, as in getting weak. If it were starting to overheat, it may not pump fuel like it is supposed to and would cause the loss of ...

Engine has no Oil Pressure when in Stop Mode, Start Cycles will wear out stress Bearings faster from low/no Oil Pressure Cycling with very short time to increase Oil Flow. Buy a new Battery, then Starter, then Engine ! EPA does it again.

The main reason for the use of a 2-stroke engine is it accelerates much faster than a similarly sized 4-stroke engine. The obvious reason for this is a 2-stroke cylinder fires on every revolution of the crank shaft, while a 4-stroke does it every other revolution. Also because the 2-stroke fires on every revolution, they only need enough weight to balance ...

I know from experience that the doors like to rust after about 7 years if you're not careful. I don't know of anything else except the usual problems like cracking radiators, blown headgaskets and broken main bearings (usually under #3 piston). Other things that go wrong include the main oil seal and the clutch. If you have a VF39 STI turbo, it might crack ...

2 stroke engines as you know must have gasoline premixed with oil. This is because that oil actually poorly lubricates as the pistons fire constantly. In a four stroke engine every cylinder fires and then makes a full rotation getting lubricated via oil jackets and cooled by water jackets running up through the block and the head of the engine(on top of the ...

It's similar to the firing order of a Subaru, which instead of an inline 4 firing, 3, 2, 4, 1, a Subaru fires two cylinders at a time, and it's because when you're riding on dirt you want a delay between firing. It gives you a pause, and more traction. When you're riding on pavement you want 12 cylinders, but even from the start line, you don't want to burn ...

Air in the coolant usually comes with a fluctuating idle. White smoke usually means headgaket has popped as coolant is being burned in the combustion process. It doesn't always mean it will overheat.

tl;dr: Ambient air temperature should generally not interfere with engine efficiency or fuel consumption, but will affect overall power output. Do not confuse efficiency with power output. These are two separate things. When your intake charge is more dense, you can throw more fuel at it and creates more power. (NOTE: The idea for the engine management ...

Wow could be a mess of things. It might not even be related to your fuel system either. But, lets start there. First, lets talk about your fuel quality. If degraded over time will cause the engine to run lousy. Either its running bad all the time, then it is from the gas or if it is not running bad all the time and just has temporary issues, then it is ...

Open the hood and listen. You can find an automotive stethoscope for more precision. If it's coming from the engine itself, try changing oil weight. If it's coming from the pulley on the left, you could try replacing the pulley. If it's coming from around the throttle body, check for vacuum leaks. For oil weight, try 30 weight oil. Here in the states, we ...

I have had plugged fuel filters do this also. Try putting some fuel injector cleaner through see what happens. I always try the cheapest first and then go from there.

A full size GM van would not be my first choice for an initial engine change. Vans can be problematic as so much of the engine is under the dash. Most of the front has to be removed, grill, core support, radiator, a/c if equipped. You'll need an engine hoist a load leveler, a good floorjack and stands. A good digital camera to take pictures of where things ...
