Looks like it is time for some maintenance. When last were the spark plugs, oxygen sensors, air filter and such changed?
Are you getting any CEL codes? How many miles on your car? It could be clogged cats.

I suggest you change all 4 oxygen sensors to narrow down the issue. The ECU reads the input signals from those sensors to determine fuel and timing for the engine.
