You detect flat spots, power loss

Top 12 reasons

Identifying a power problem can try the patience of a saint, and doubly so when the drop in oomph occurs intermittently, virtually guaranteeing that your mechanic won't be able to reproduce it. Thankfully, there are some clear signs to look for.

  Do you lose power on your engine or have you flat spots ?

Try Carbon Cleaning !

After the decarbonization these problems disappeared !

Preventive engine cleaning enables you to restore engine parts rather than replacing them, thereby saving vehicle owners on costly parts, such as a new turbocharger (1.350€ - 3.100€), catalytic converter (600€ - 2.000€), DPF (600€ - 2.000€) or EGR valve (370€ - 500€).

These problems result mainly from poor combustion, which stifles the engine.

So before replacing your engine parts, try Carbon Cleaning. A dirty engine as the result of carbon deposits is the new threat to vehicle performance.

Make your online diagnosis
Air filter
An engine's air filter is meant to pull impurities and can become clogged resulting in low air intake and low power. Remove and change your air filter.

Engine light is on
If engine problems exist and the service or check engine light is on, use a code reader to retrieve the codes to make necessary repairs.

Engine misfire
If an engine is running poorly it can result in low engine power output, an engine tune up or fouled spark plug can cause engine misfire performance issues.

Fuel system filter
The fuel system filter is designed to remove particles from the fuel itself, when a filter becomes plugged the system fails to supply pressure to the injectors, this filter must be replaced at regular intervals to maintain proper performance. (Note: Some vehicles fuel filter is inside the fuel tank and is non serviceable.)

Fuel pump
A fuel pump is designed to supply a consistent pressure to the fuel injection system, when this pump becomes weak it can lose this pressure resulting in low fuel pressure causing the aforementioned low power output.

Catalytic converter
A catalytic converter is designed to incinerate excess fuel remnants resulting in cleaner engine exhaust output gasses, if the unit bcomes clogged or broken the engine's power will be reduced while restricting exhaust flow.

Mass air flow sensor
A mass air flow sensor measures the volume of air consumed by the engine at any giving time, this sensor is subject to contamination which can effect the data feedback to the computer causing low engine power.

Engine compression
A plugged catalytic converter can cause low engine power by not allowing the engine exhaust to exit the engine properly.  

Timing belt or chain
The crankshaft and camshaft must stay in proper correlation, if a timing belt or chain is improperly installed or becomes loose and jumps a tooth or two the engine will produce less power, disassemble the timing cover to check timing marks.

This problem pertains to older engine that utilize an adjustable distributor. If the timing is adjusted too far advanced or retarded (in front or behind the timing mark) in relationship to the engine crankshaft engine will have low power output. To check the ignition timing adjustment a timing light is needed. If the engine timing is way off ( 20 degrees or more ) check the timing belt or timing chain, crankshaft camshaft correlation.

Transmission slip
Occasionally the engine will feel like it has good power, but its not getting to the wheels, this condition is caused by transmission slip. Both, standard and automatic transmissions retain a clutch or clutches that when become worn through usage, can lose their grip and slip causing heat due to the transference of energy developed from the engine while failing to propel the vehicle.

Harmonic balancer
The engine ignition timing is based off of the crankshaft harmonic balancer, which can become loose causing the crankshaft woodruff key to dig into the balancer timing (location) slot causing the timing to become retarded causing low power, to check for this condition remove the harmonic balancer and inspect.
