The weight of the Z7X engine according to the catalog is 190 kg. The engine number L7X is located to the right of the oil filter. The most frequent service requests are related to the engine not starting, stalling, or jerking due to a faulty sensor. Often, fuses and relays burn out, wiring deteriorates, and contacts oxidize, especially if the car is idle for a long time. The engine speed fluctuates. Unstable engine operation is usually caused by air suction through cracks in the vacuum tubes leading to the MAP sensor. Less frequently, it is due to a dirty throttle valve or a fuel pump malfunction. Unreliable ignition system regularly leads to engine misfires. The cause may be the coil, distributor, high-voltage wires, or spark plugs.
