Although changing the spark plugs and O2 sensor tend to fix this type of issue, it could also be caused by dirty fuel filter, clogged fuel injector lines, or another electrical gremlin.

So, even relatively minor stuff, such as incorrect timing, or a clogged fuel injector, fuel filter or air filter, could be at fault here.

Not exact matches

If it seems low, try replacing the fuel filter and inspect the fuel injectors to make sure they aren't leaking or clogged.

This leads me to believe that there is another issue present, something like unmetered air or partially - clogged injectors which the fuel management can not accommodate for due to the absence of lambda feedback.

In the event your fuel injectors are exceptionally clogged you may demand an expert fuel system cleaning.

Fuel injectors clog when deposits build up over time and thousands of miles; when that happens, they don't deliver the fine mist of gas that provides maximum performance and efficiency.

Detergents have been required by the EPA since 1995 because many vehicle owners complained of clogged injectors and fuel - system deposits.

For example, pouring injector cleaner into the tank can loosen the dirt inside the tank and fuel lines and clog the injectors instead of cleaning them.

Possible factors include poor compression (dirty piston rings, scored cylinders, dirty or worn valves), dirty fuel injectors, dirty cooling system, dirty and partially clogged catalytic converter.

If an injector is really clogged up then no amount of Seafoaming or running fuel injector cleaner through the fuel tank will fix it.

Using oxidized gasoline is a bad idea, since the gum can clog your fuel filter, create deposits in your fuel system (especially the injectors), and generally hurt performance.
