An old oxygen sensor (say, 90,000 miles or more) may still work well enough that it doesn’t trigger the check engine light but could still hurt fuel economy. Engine performance can also be reduced by more serious internal problems, such as valves that don’t seat properly or worn piston rings, or by restrictions in the exhaust system. Because the same symptoms can suggest different problems, and there are often several possible causes and cures, it’s better to consult a professional mechanic than to try to be one if you have neither the experience nor the right equipment to diagnose drivability problems. In short, rather than ask for a tune-up, tell a mechanic what you’re experiencing and ask him or her to find the cause.
This auto electric repair tool consists of many parts that help in completing the above functions as efficiently as possible. The engine analyzer has the following built in components: Timing light, Ammeter, Ohmmeter, Vacuum pump and gauge, Oscilloscope, Pressure gauge, Exhaust analyzer etc. All these components can be used in the most common engine types i.e. both diesel and gas powered.
