Is your engine losing power?

If the process of nailing down the causes of power loss were as simple as a tuber in the tailpipe, we wouldn’t make such a mess out of diagnosing them. But identifying a power problem can try the patience of any person, even a saint. When the drop in car power occurs occasionally, you can guarantee that your mechanic won’t be able to reproduce it. But what if you just don’t have time to get it checked out by your mechanic? Thankfully, there are some clear signs to look for when judging why your car is losing power.

Not receiving any power

If your vehicle loses power when you put the pedal to the metal, the odds are good that a fuel system malfunction is preventing your engine from drawing the extra oomph it needs to accelerate. You could be looking at a leaking fuel line, a clogged injector, gummed-up filter or an exhausted fuel pump.

A smoking exhaust

A backfiring or smoking exhaust can indicate either too much fuel or too little spark, both of which can bring about power loss in any car. Whether it is pre-owned cars in South Africa or new cars from Japan. A backfire occurs when the fuel-air mixture does not fully flare up in the combustion chamber, but instead pops off elsewhere in the car’s system.

Spark plugs covered with engine oil, ash or other deposits will misfire, the same as plugs with partially melted electrodes. Black smoke from your exhaust might point to spark problems, which can damage your engine, so check them as soon as you can.

A shaky steering wheel

Wen idling at red traffic light or anywhere else, does your engine tremble? Does it send tremors through the steering wheel or into the rest of the vehicle, which then results in a noticeable loss of power? If so, misfiring cylinders are to blame for this mishap.

Engines normally misfire for three reasons: lost compression, spark loss or bad air-to-fuel ratio. Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss.

Struggling to go up an incline

If your vehicle cuts out or struggles to go up an incline it could signify that it has a clogged fuel filter.  As the filter eliminates gunk from your fuel, it gradually accumulates dirt. This then causes the fuel pump to work harder to shove fuel through it. In high-demand circumstances, such as driving up a hill, it might not be able to deliver enough gas to get the job done. Get your car checked out with a fuel pressure test or digital scope.

If you are still not sure what could be slowing down power to your car’s engine then it’s best to take it to a qualified mechanic. These are specialist in the trade and will be able to tell you a whole lot more.
