I had a similar problem with my navara bakkie - appears it was the fuel filter allowing air into the system. Replaced this and changed the clamps on the fuel lines where they join the fuel filter. Seems to have worked.

I'd like to pretend I'm an authority on this kind of stuff but I just have another opinion, just like most. Here are some technical differences between a modern bike and your 'new' Royal Enfield. Modern bikes have a coating on the inside of the cylinder wall on top of the iron (essentially) sleeve...or in some cases...straight aluminum alloy...really, I'm ...

I would not consider this an issue. What is happening is, as you've probably already figured out, is that your car is adjusting itself to the higher altitude. When the light comes on, it is telling you it is basically out of calibration (probably due to running too rich at the higher altitude). Once the computer can get caught up and adjusts the fuel map ...

As gasoline burns, it expands. When an engine is operating smoothly and efficiently, the space above the piston will expand at roughly the same speed as the burning gasoline inside. If that happens, the force on the piston will be relatively constant throughout the stroke. If an engine is rotating more slowly, the much of the fuel will burn before the ...

You won't damage a vehicle by shutting it off before it gets to full operating temperature. This, in some places, could be considered a waste of gas. There are two things you need to be aware of though. If you are continually doing this on a regular basis, you will cause condensation in the crank case. This excess moisture can contaminate the oil and ...

It's more than likely the serpentine belt at the alternator making the noise. One of two things going on here, either the belt itself is worn out, or the tensioner is not providing the preload to the belt to keep it tight. After the belt warms up a little bit, it sticks a little better so the sound goes away. If you haven't replaced the belt in a while, I'd ...

Your idle air control valve might be dirty. Try cleaning that.

I make no claim to be a Subaru expert but I have become aware of issues with the variable valve timing on GM vehicles. It seems some vehicles with this type of valve train are sensitive to oil viscosity. Oil that is too thick or to thin can result in poor performance. Is it possible that you added the wrong type of oil? If oil was induced into the exhaust ...

Depending on the colour of the smoke that is produced from the exhaust it could be different sources, have you had a valve cover replacement done on the car? I've worked on some cars that have leaking valve covers where the spark plugs are located and this causes issues with oil seeping into the cylinders, which could be a source of smoke, and oil loss. ...

It's your transmission. Your torque converter is bad. There is too much torque as a result. When your car is in neutral or park there is no torque being created. When you leave the in gear idle state, the torque is relieved. That is why the problem will go away when you hit the gas. Hope this helps

I have seen similar symptoms with vehicles that have a semi-clogged fuel filter on gravity fed machines. The blockage prevents full flow of the fuel. The consumption of fuel driving at higher RPM's exceeds the fuel flow and the engine dies. Once the fuel refills the carb float bowls the engine is able to start again. Perhaps this is the issue.

Do you have any idea about potential power level of 132 kW (180 HP), 700 Nm MAN truck (TGL) 4.5 litre engine with damaged (not working) turbo? As a rule of thumb, for every atmosphere's worth of boost, you'll double the amount of power the amount the engine puts out naturally aspirated. For instance, if an engine puts out 100hp naturally aspirated, the ...

I appears to be coming from the front and the center of the engine. I could be a hose near the water pump. The water pump itself may have failed. Most water pumps have a weep hole that drips when the seals fail. It is on the bottom of the pimp and difficult to see. You may be able to feel it by reaching under the pump, it is a small hole about half the ...

From the lack of information in your post, the only thing I can surmise is your catalytic converter is plugged. With the age of your vehicle and the notice that it will not "pick up speed", this is the only thing which is coming to mind. Several things you can check. If the engine idles just fine while the vehicle is in park, but when you rev it up, it will ...

Feels like a governor of some sort.. has it already been chipped? If it's reliably getting to EXACTLY the same speed and maintaining it, I'd start to suspect that it was designed to be limited to that. Is it actually hitting an RPM limit, or a MPH limit? (read: how many RPMs is it doing @96MPH?) Sounds like a built-in MPH limit. I found a reference to a ...

Corsa's (actually Vauxhalls/Opels in general) sometimes have noisy hydraulic lifters. I drove mine for 60 thousand kilometers with this noise before I upgraded to a Turbo Coupe and gave the car to my mom. No problems so far. The Coupe had the same stupid tick. Again, I drove it for 30 thousand kilometers before trading it in for a Subaru Forester XT. Only ...

I think this is a dual overhead camshaft engine. In that case, one of your lifters or springs may be going bad. This would slow down the return of the lifter as the cam moves away from it. that would create a momentary space and then a click when the lifter contacts the cam again. Just a guess. Your mechanic probably has a modified stethoscope that he (or ...

Injectors or spark plug leads (if not using coil packs). When was the last time u changed your plugs? Also check for tears in vacuum hoses. Though usually vacuum leaks symptoms wouldn't disappear.

This is a two cycle engine This particular motor (and most Derbi's) is a 2-stroke engine and as such has multiple places where an air leak from the reed valve (intake track after the manifold) all the way through to the head gasket, base gasket, spark plug AND crank seals can give you a no-compression issue. Things to check Reed Valve* The reed valve ...
