car is running lean or nonthing being shown on the air/fuel ratio gauge at idle, no horsepower, this is a 1.6 liter, twin cam 16 value, fuel injected, engine is a little shaking at idle, the whole car shakes while driving or when start driving from a stop in 1st gear, it acts like it can barely start when turning on the car, have had the issue before, i resolved it by stepping down the gears and brought it back up to gear or at other times started driving in 1st gear and then the horsepower came back, can u help me?

Could be your clutch is slipping or the exhaust system has excessive backpressure due to a clogged-up catalytic converter.
