When checking and troubleshooting engine problems, it is important to start by checking the condition of the main systems. If one of the following problems occurs - the engine does not start, unstable idle speed, weak acceleration - first of all, you need to check the following main systems:

Electrical power (battery, fuse connection, fuses).

Grounding of the body.

Ignition system (spark plugs, high voltage wires, ignition coil).

Fuel system (fuel lines, fuel filters, fuel pump).

Exhaust emission control system (PCV system, EGR system, leak).
