Hello there, thank you for asking about your 2005 Ford Ranger. This is not an engine size or type used in our American version of the truck and I can only recommend having the intake system opened up with a...

Warped manifolds are a well known problem on the 5.4L engine. My personal F150 has a noticeable exhaust leak from the manifolds on cold start, but goes away once the engine warms up and the manifolds expand. As for adding...

The 5.9L diesel is a straight six engine. The 6.6L diesel and the 7.3L diesel are both V8 engines. If find that there are more maintenance when it comes to the V-configured engines to the straight six engines. I have...

There are many possible malfunctions that can cause a engine to stall (https://www.yourmechanic.com/services/car-is-stalling-inspection). As long as the engine is in good mechanical condition, it comes down to the engine getting the correct air/fuel supply, a sufficient ignition to fire the...

From what you describe it would appear that your vehicle is experiencing some sort of engine performance issue. Hesitation when put into gear can be caused by a wide variety of things. Possible causes can range from issues with the...

If you want to add some more power easily to your vehicle I would recommend an intake system or an exhaust system or both. The intake system and the exhaust system are two of the easiest ways to add power...

If the engine is running as poorly as you describe, it will actually be cheaper to pay the diagnostic fee so that the correct repair can be made rather than to continue to waste fuel. Obviously, a poorly running engine...

From what you describe it would appear that an exhaust leak may be affecting your engine's performance. If the leak appears to come and go, then the first thing I would do is look at the vehicle's EGR valve and...

Hello. The engine knock sensor is retarding the ignition timing to match what the lower octane fuel can support in terms of “timing advance.” There is nothing to worry about. The engine computer is just operating the engine so as...

Hi there. The engine will not start to break down or lose power at that point. The factory engine does not make that much power on its own so I have to assume you are talking about aftermarket power modifications....

When your engine computer sees a problem with a major sensor or sees that an engine is misfiring, the computer will turn on the restricted performance statement with a red or amber light. The problem may be one of several,...

There are quite a few issues that can cause a four cylinder engine to lose compression on all cylinders. Unfortunately, none of them are what would be considered inexpensive. There could be a problem with the timing chain, camshaft problem,...

Hello - the best way to keep your Altima running like new is "attentive maintenance (https://www.yourmechanic.com/scheduled-maintenance/nissan-altima/?year=2009&mileage=150000)". Keep fluids (oil, transmission fluid, coolant) topped off and changed at recommended intervals. If your timing chain and associated components (tensioner, idler, chain guides,...

There are zero options to "improve" the acceleration of the vehicle very simply because if such "options" actually existed Toyota would have already implemented them on the assembly line. That is who wouldn't want better acceleration? Toyota selected and tuned...

Hello. The "blow-off-valve" or BOV, is a pressure-release valve designed to prevent over-pressurization of the engine, not the turbocharger itself. While hearing some of the sounds a turbo-charged engine (https://www.yourmechanic.com/article/how-a-modern-engine-works) makes while running through the gears is a most pleasant...

The symptoms you are describing are almost always caused by a bad catalytic converter (https://www.yourmechanic.com/services/catalytic-converter-replacement). When this fails it clogs the exhaust, which causes these problems to occur. Do a back pressure test on the exhaust first. If that is...

Hello. Due to the design of the engine, there's not much that can be done, aside from completely rebuilding the engine, to achieve high rpm power. Typically V layout engines are designed to provide low end torque and a smooth...

Taking on a project such as this takes lots of time, even for the most experienced mechanic. You will be re-engineering your car and this will require you to learn a lot and make a lot of decisions. There is...

If you compare the concept to some small remote control cars and trucks out there, they have a two speed rear ends to have great low speed torque and use shift gears to have great high speeds. When it comes...
