As the main driver, you know better than anyone how your car runs, so when it loses power, you’ll be the first to spot it. So why does your car lose power? Well, typically, it’s down to four main areas: fuel delivery, ignition, exhaust circulation, or engine issues. The final possible culprit is a faulty cooling system.
To get your car back to full power and its regular performance, first, you’ll have to pinpoint the problem. Fixter is ready to help. We’ve got an excellent network of qualified mechanics ready and waiting to get your car back to its optimum performance.
Why does a car engine lose power?
There are plenty of parts that will cause your car to feel sluggish when they stop working correctly: choked up fuel filters and injectors, backfiring or clogged exhausts, blocked catalytic convertors, loose timing belts, failing spark plugs and more. The list is pretty long, including minor, simple issues, right up to severe and costly problems.
They can be mechanical, electrical, electronic, or just down to poor maintenance and upkeep. Whatever’s causing your car to run slower than usual, you need to fix the problem before it leads to real and long-term damage.
What are the common causes of car engine loss of power?
Problems with the fuel delivery
Risk level – Medium
What to do – Locate the problem part and have it cleaned, repaired or replaced.
One of the most common problems with loss of power is something preventing the smooth flow and delivery of fuel into the engine. It could be down to your fuel pump, clogged fuel injectors (they collect dirt over time), a blocked DPF (diesel particulate filter—a component that burns off debris, generally at higher speeds), or finally, the king culprit, a clogged fuel filter.
The fuel filter is designed to prevent dirt and debris from entering the fuel system. Over time, they become clogged with all the contaminants they capture, and if you don’t replace them, they’ll slow down the delivery of fuel, causing poor engine performance.
Issues with the exhaust system
Risk level – Medium
What to do – Have the exhaust checked for blockages and leaks.
To operate at maximum efficiency, your engine needs to clear the exhaust gasses and take in clean air for the next combustion cycle. With a faulty exhaust system, your engine is effectively choked, preventing it from reaching full power.
A backfiring exhaust is the result of a poor fuel and air mix, with the unburned fuel igniting on the hot metal of the exhaust. Backfiring is usually a symptom of a faulty fuel pump.
Problematic blockages can happen throughout your entire exhaust system, but commonly in the catalytic converter. A clogged cat will back up exhaust gasses, causing poor performance.
Risk level – High
What to do – Have a professional determine the cause and correct it immediately.
Given that it’s your engine that powers the car if there’s a drop in power, that’s one of the first areas to check. So what are the components that can cause a reduction in power? Well, your timing belt, turbocharger, anything that drops pressure
